                               DATALINK.NET, INC.

               Incorporated Under the Laws of the State of Nevada

No. A-1 150,000 Common Stock                                 Purchase Warrants

                          CERTIFICATE FOR COMMON STOCK
                                PURCHASE WARRANTS

     1. Warrants. This Warrant Certificate certifies that ANTHONY N. LAPINE, or
registered assigns (the "Holder"), is the registered owner of the
above-indicated number of Warrants expiring on December 1, 2004 ("Expiration
Date"). One (1) Warrant entitles the Holder to purchase one share of common
stock, $.01 par value ("Share"), from Datalink.net, Inc., a Nevada corporation
("Company"), at a purchase price of $4.75 per share ("Exercise Price"),
commencing December 1, 1999, and terminating on the Expiration Date ("Exercise
Period"), upon surrender of this Warrant Certificate with the exercise form
hereon duly completed and executed with payment of the Exercise Price at the
offices of the Company, 1735 Technology Drive, Suite 790, San Jose, California
95110.

     2. Transfer of Warrants. The Warrants represented by this Warrant
Certificate shall not be transferable except upon the death of the Holder and
then only to the estate of the Holder or pursuant to the Holder's will or the
applicable laws of descent and distribution.

     3. Exercise of Warrant. The Warrant may be exercised in whole or in part at
any time on or before the Expiration Date upon surrender of the Warrant in
conjunction with Form of Election to Purchase and the payment at the Exercise
Price stipulated above. If the Warrant is exercised in part, then the Holder
shall be entitled to receive a new Warrant covering the remaining number of
Warrant Shares not exercised.

     4. Expiration of Warrants. No Warrant may be exercised after 5:00 p.m.
Pacific Time on the Expiration Date and any Warrant not exercised by such time
shall become void, unless the Expiration Date of this Warrant is extended by the
Company.

     5. Adjustment of Exercise Price. After each adjustment of the Exercise
Price pursuant to this paragraph 5, the number of shares of Common Stock
purchasable on the exercise of each Warrant shall be the number derived by
dividing such adjusted pertinent Exercise Price into the original pertinent
Exercise Price. The pertinent Exercise Price shall be subject to adjustment as
follows:

          In the event, prior to the expiration of the Warrants by exercise or
     by their terms, the Company shall issue any shares of its Common Stock as a
     share dividend or shall subdivide the number of outstanding shares of
     Common Stock into a greater number of shares, then, in either of such
     events, the Exercise Price per share of Common Stock purchasable pursuant
     to the Warrants in effect at the time of such action shall be reduced
     proportionately and the number of shares purchasable pursuant to the
     Warrants shall be increased proportionately. Conversely, in the event the
     Company shall reduce the number of shares of its outstanding Common Stock
     by combining such shares into a smaller number of shares, then, in such
     event, the Exercise Price per share purchasable pursuant to the Warrants in
     effect at the time of such action shall be increased proportionately and
     the number of shares of Common Stock at that time purchasable pursuant to
     the Warrants shall be decreased proportionately. Any dividend paid or
     distributed on the Common Stock in shares of any other class of the Company
     or securities convertible into shares of Common Stock shall be treated as a
     dividend paid in Common Stock to the extent that shares of Common Stock are
     issuable on the conversion thereof.

     6. Adjustments for Reorganization, Consolidation, Merger, or Sale of
Assets. If at any time while the Warrant, or any portion thereof, remains
outstanding and unexpired, should there occur a reorganization, merger, or
consolidation; or should there occur a sale or transfer of the Company's assets
or properties substantially in entirety as part of a reorganization, merger or
consolidation, then lawful provision shall be made so that the Holder shall
thereafter be entitled to receive upon exercise of the Warrant, or any unexpired
exercisable portion thereof, the number of shares of stock or other securities
or property of the successor corporation resulting from such reorganization,
consolidation, merger, sale or transfer that the Holder would have been entitled
to if the Warrant, or portions thereof, had been exercised immediately prior to
the event. The foregoing shall apply similarly to any successive
reorganizations, consolidations, mergers, sales or transfers that may occur
while the Warrant, or any portion thereof, remains exercisable.

     7. Reservation of Stock Underlying the Warrant. At all times until the
expiration of the Warrant, the Company will authorize, reserve, and keep
available, solely for issuance and delivery upon the exercise of the Warrant,
the shares of Common Stock of the Company that shall be receivable upon exercise
of the Warrant.

     8. Underlying Stock to be Fully Paid and Non-Assessable. The Company
covenants that the shares of Common Stock issuable upon exercise of the Warrant
shall be duly and validly issued, fully paid, non-assessable, and free of any
liens, charges, and all taxes with respect to the issue thereof.

     9. No Impairment. The Company shall not, by amendment of its Certificate of
Incorporation or other method or venue, avoid or seek to avoid the observance or
performance of any of the terms of the Warrant, but shall at all times, in good
faith, take all such actions as may be necessary or appropriate in order to
protect the rights of the Holder thereunder against impairment.

September 7, 1999

Mr. Anthony LaPine
Chief Executive Officer
Datalink.net, Inc.
1735 Technology Drive
Suite 790
San Jose, CA 95110

                            PERSONAL AND CONFIDENTIAL

Dear Tony:

     This letter agreement (the "Agreement") confirms the terms and conditions
of the engagement of The Seidler Companies Incorporated ("TSC") by Datalink.net,
Inc. ("Datalink" or the "Company") to render certain financial and advisory and
investment banking services to Datalink in connection with a proposed $5 million
to $10 million public or private financing (the "Transaction").

     TSC's principle business is to provide financial, consulting and investment
banking services to corporate clients.

     Datalink has advised TSC that Datalink requires additional capital in order
to consummate its business plan.

1. In order to finance Datalink, TSC agrees to perform the following services
(the "Services"):

     (a)  At Datalink's request, review current and historical financial and
          operating information of the Company;

     (b)  At Datalink's request, help the Company prepare an executive summary
          of its business plan;

     (c)  At Datalink's request, advise and assist the Company in its due
          diligence investigation of any potential investor;

     (d)  At Datalink's request, advise and assist the Company in negotiations
          with any potential investor;

     (e)  At Datalink's request, advise and assist the Company in the valuation
          and structuring of a financing.

2. The Company agrees to pay TSC for its services as follows:

     (a)  A retainer fee of 10,000 shares of Datalink common stock with
          appropriate restrictions upon the signing of this Agreement, one half
          (or 5,000 shares) to be granted upon the

<PAGE>   2

          signing of the Agreement, and the remaining five thousand (5,000)
          shares to be granted in installments of 1,000 shares per month for the
          next five months;

     (b)  A success fee based upon the type of financing arranged by TSC, but in
          no event shall the fee exceed five percent (5%) of the total money
          raised by TSC's financing efforts. If other third parties assist the
          Company in raising money, the total success fee of 5% will be divided
          among all parties, based upon each party's services to the Company.

3. The term of this Agreement shall commence on the date hereof and end 12
months thereafter. This Agreement may be renewed upon mutual written agreement
of TSC and the Company. Either party may terminate this Agreement at any time by
giving the other party at least thirty (30) days prior written notice of such
termination, at which time the Company shall pay to TSC all fees earned and all
reasonable expenses incurred, in accordance with Paragraphs 2 and 4 hereof. The
Company agrees to pay TSC any fees specified in paragraph 2 if the events
specified therein shall occur during the term of this Agreement. Any obligation
pursuant to this Paragraph 3 shall survive the termination or expiration of this
Agreement.

4. The Company agrees to reimburse TSC for all of its reasonable out-of-pocket
fees, expenses and costs (including, but not limited to, travel, accommodations,
telephone, computer, courier and supplies) in connection with the performance of
its activities under this Agreement, provided that such expenses do not exceed
five hundred dollars ($500) in any single month without prior approval by the
Company. All such fees, expenses and costs will be billed monthly and are
payable when invoiced. Upon termination or expiration of the Agreement, any
unreimbursed fees and expenses will be immediately due and payable. Any
obligation pursuant to this Paragraph 4 shall survive the termination or
expiration of this Agreement.

5. In addition to the payment of fees and reimbursement of fees and expenses
provided for above, and regardless of whether a Transaction is consummated, the
Company agrees to indemnify TSC with regard to the matters contemplated herein,
as set forth in Appendix A, attached hereto, which is incorporated by reference
as if fully set forth herein. This Paragraph 5 shall survive the termination or
expiration of this Agreement.

6. Each party agrees that, except as compelled by law, it will not disclose the
services or advice to be provided by TSC under this Agreement publicly or to any
third party without the prior written approval of the other party.
Notwithstanding, TSC shall be permitted to advertise the services it provided in
connection with this financing subsequent to a consummation of the financing.

7. In providing the Services, TSC acknowledges that it shall have no authority
to bind the Company in any respect.

8. Any and all information, in any form, given by the Company to TSC shall be
treated as confidential, whether or not it is labeled as such. This information
shall be treated in a manner no less restrictive than the strictest procedures
used by TSC to protect its own confidential information. TSC agrees not to
disclose this information to others except to those employees who are required
to have the information in order to carry out the contemplated purposes
described in this Agreement. TSC agrees to notify the Company in writing of any
misuse or misappropriation of such confidential information. TSC's obligation
under this paragraph shall survive for two years after the termination of this
Agreement. Any

<PAGE>   3

materials or documents which have been furnished to TSC in accordance to this
agreement will be promptly returned at the Company's request, or upon
termination of the Agreement.

9. This Agreement shall be governed by and construed in accordance with the laws
of the State of California without regard to the conflict of laws or provisions
thereof and may not be amended or modified except in a writing signed by both
parties.

10. This Agreement and all rights, liabilities and obligations hereunder shall
be binding upon and inure to the benefit of each party's successors but may not
be assigned without the prior written approval of the other party.

11. In the event a disagreement between the parties cannot be resolved, the
parties mutually agree to resolve any conflicts through arbitration proceedings.

     Please confirm that the foregoing correctly sets forth our agreement by
signing the enclosed letters in the space provided and returning them to use for
execution, whereupon we will send you a fully executed original letter which
shall constitute a binding agreement as of the date first above written.
