         WHEREAS, GigaPixel desires consulting and similar services relating to
GigaPixel's business; and

         WHEREAS, Consultant desires to contract with the Company to perform

Bonus").

         4. Repayment Obligation. Concurrently herewith, the Consultant shall

Notwithstanding the foregoing, the Note shall also provide that if the

            (b) Assignment of this Agreement to a subsidiary, parent, successor
or affiliate of the Company.

         5. Consulting Fees. The Company agrees to pay the Consultant a flat fee

         6. Payments. The Company shall reimburse the Consultant for
out-of-pocket expenses reasonably incurred by the Consultant in the performance
of the Services upon the Consultant's submission of any request for
reimbursement in a format consistent with the Company's policies from time to
time in effect.

         7. Confidentiality. The Consultant acknowledges that Confidential
Information (as defined in Section 8 of this Agreement) is of great value to the
Company. Accordingly, the Consultant agrees not to divulge to anyone, either
during or after the term of this Agreement, any Confidential Information
obtained or developed by the Consultant during the term of this Agreement. Upon
the expiration or earlier termination of this Agreement, the Consultant agrees
to deliver to the Company all documents, papers, drawings, tabulations, reports
and similar documentation which are furnished by the Company to the Consultant

source other than the Company or 3dfx, provided that such source is not bound by
a confidentiality agreement with the Company or 3dfx.

         9. Termination. The Company shall have the right to terminate this
Agreement at any time upon 15 days prior written notice to the Consultant. In
addition, in the event either party fails to cure a breach of this Agreement
within fifteen (15) days after receiving written notice thereof, then the
non-breaching party may terminate this Agreement upon written notice to the
breaching party. In the event of any termination of this Agreement, the Company
shall make payments to the Consultant for all work performed in accordance with
the terms and conditions of this Agreement up to the date of termination, and
the Consultant shall immediately return to the Company, without limitation, all
correspondence, reports, documents, drawings and any other items of whatever
nature supplied to the Consultant by the Company or owned by the Company
pursuant to this Agreement.

         10. Independent Contractor/Taxes. The Consultant is not an agent or

                            NONCOMPETITION AGREEMENT

     THIS NONCOMPETITION AGREEMENT (the "Agreement") made and entered into as of
the 20th day of July, 2000, by and among 3dfx Interactive, Inc., a California
corporation ("Buyer"), and George T. Haber ("Promisor").

                                   WITNESSETH:

     WHEREAS, pursuant to the Agreement and Plan of Reorganization dated as of
March 27, 2000 (the "Purchase Agreement"), by and among Buyer, Galapagos
Acquisition Corp., a Delaware corporation and the wholly-owned subsidiary of
Buyer ("Galapagos"), and GigaPixel Corporation, a Delaware corporation (the
"Company"), Galapagos shall merge with and into the Company and the Company
shall be the surviving corporation in the Merger (as defined in the Purchase
Agreement);

     WHEREAS, the Purchase Agreement provides, as a condition to the closing
thereunder, that Promisor shall execute and deliver this Agreement;

     WHEREAS, the agreements of Promisor hereunder are an important aspect of
the transactions under the Purchase Agreement, and Buyer would not consummate
such transactions absent the execution and delivery by Promisor of this
Agreement;

     WHEREAS, the Company has been and is presently engaged in the development,
implementation, license, sale and/or other distribution of high-performance 3D
graphics hardware and software (the "Business") in and around the territories
specified in Schedule I attached hereto (collectively, the "Territory");

     WHEREAS, Promisor and Promisor's affiliates have substantial financial
resources, experience in the Business and the ability to operate a business or
businesses that could compete with the Company in the Business or in related
businesses following the Closing; and

     WHEREAS, the agreements of Promisor hereunder are reasonable and necessary,
both in scope and duration, to protect the business and goodwill of the Company
that will be acquired pursuant to the Purchase Agreement, and the Company would
suffer damages, including the loss of profits, if Promisor or any of Promisor's
affiliates engaged, directly or indirectly, in a competing business with the
Company or Buyer.

     NOW, THEREFORE for and in consideration of the premises and of the mutual
representations, warranties, covenants and agreements contained herein, and of
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, and upon the terms and subject to the conditions
hereinafter set forth, the parties do hereby agree as follows:

     1. Consideration; Disclosure of Information. For and in consideration of
the sum of $700,000, the receipt and sufficiency of which are acknowledged by
Promisor, Promisor agrees that for a period of three (3) years from the date
hereof, without the prior written consent of Buyer, Promisor shall not, directly
or indirectly, through any form of ownership, in any individual or
representative or affiliated capacity whatsoever, except as may be required by
law, reveal, divulge, disclose or communicate to any person, firm, association,
corporation or other entity in any manner whatsoever information of any kind,
nature or description concerning: (i) the names of any prior or present
suppliers or customers of the Company or Buyer, (ii) the prices for which the
Company or Buyer obtains or has obtained products or services, (iii) the names
of the personnel of the Company or Buyer, (iv) the manner of operation of the
Company or Buyer, (v) the plans, trade secrets, or other confidential or
proprietary data of any kind, nature or description, whether tangible or
intangible, of the Company or Buyer, or (vi) any other financial, statistical or
other information that the Company or Buyer designates or treats as confidential
or proprietary. The agreements set forth herein shall not apply to any
information that at the time of disclosure or thereafter is generally available
to and known by the public (other than as a result of a disclosure directly or
indirectly by Promisor in violation of this Agreement), the disclosure of which
is required by law, regulation, order, decree or process or is otherwise
approved by the Company or Buyer. Without regard to whether any or all of the
foregoing matters would be deemed confidential, material or important, the
parties hereto stipulate that as between them, the same are important, material
and confidential and gravely affect the effective and successful conduct of the
Business and its goodwill.

<PAGE>   2

    2. Noncompetition. Promisor agrees that for a period of three (3) years from
the date hereof, Promisor shall not:

        (i) Call upon, solicit, divert, take away or attempt to call upon,
    solicit, divert or take away any past, existing or potential customers,
    suppliers, businesses, or accounts of (a) the Company or (b) the Business in
    connection with any business substantially similar to the Business in the
    Territory;

        (ii) Hire, attempt to hire, contact or solicit with respect to hiring
    for Promisor or on behalf of any other person any present or future employee
    of the Company or Buyer in the Business;

        (iii) Engage in, or give any advice to any person, firm, partnership,
    association, venture, corporation or other entity engaged in, a business
    substantially similar to the Business in the Territory;

        (iv) Lend credit, money or reputation for the purpose of establishing or
    operating a business substantially similar to the Business in the Territory;

        (v) Do any act that Promisor knew or reasonably should have known might
    injure the Company or Buyer; and

        (vi) Without limiting the generality of the foregoing provisions,
    conduct a business substantially similar to the Business, whether or not
    under the name "GigaPixel" or any other trade names, trademarks or service
    marks used by the Company or Buyer in the Territory.

    The covenants in subsections (i) through (vi) are intended to restrict
Promisor from competing in any manner with the Company or the Business in the
activities that have heretofore been carried on by the Company. The obligations
set forth in subsections (i) through (vi) above shall apply to actions by
Promisor, through any form of ownership, and whether as principal, officer,
director, agent, employee, employer, consultant, shareholder or holder of any
equity security (beneficially or as trustee of any trust), lender, partner,
joint venturer or in any other individual or representative or affiliated
capacity whatsoever. However, none of the foregoing shall prevent Promisor from
being the holder of up to 5.0% in the aggregate of any class of securities of
any corporation engaged in, directly or indirectly, the activities described in
subsections (i) through (vi) above, provided that such securities are listed on
a national securities exchange or reported on Nasdaq.

    3. Enforcement of Covenants.

    3.1 Promisor acknowledges that a violation or attempted violation of any of
the covenants and agreements in Sections 1 and 2 above will cause such damage to
Buyer and the Company as will be irreparable, the exact amount of which would be
difficult to ascertain and for which there will be no adequate remedy at law,
and accordingly, Promisor agrees that Buyer and the Company shall be entitled as
a matter of right to an injunction issued by any court of competent
jurisdiction, restraining such violation or attempted violation of such
covenants and agreements by Promisor, or the affiliates, partners or agents of
such Promisor, as well as recover from Promisor any and all costs and expenses
sustained or incurred by Buyer and the Company in obtaining such an injunction,
including, without limitation, reasonable attorneys' fees. Promisor agrees that
no bond or other security shall be required in connection with such injunction.
Promisor further agrees that the periods of restriction set forth in Sections 1
and 2 above shall be tolled during any period of violation thereof by Promisor.
Any exercise by Buyer or the Company of their respective rights pursuant to this
Section 3 shall be cumulative and in addition to any other remedies to which
Buyer or the Company may be entitled. Each party represents and warrants that it
has been represented by counsel in the negotiation and execution of this
Agreement, including without limitation the provisions set forth above in this
Section 3(a) concerning the recovery of attorney's fees.

    3.2 Promisor understands and acknowledges that each of Buyer and the Company
shall have the right, in its sole discretion, to reduce the scope of any
covenants set forth in Sections 1 and 2, or any portion thereof, without
Promisor's consent, effective immediately upon receipt by Promisor of written
notice thereof; and Promisor agrees that Promisor shall comply forthwith with
any covenant as so modified, which shall be fully enforceable as so revised in
accordance with the terms of this Agreement.

                                      -2-
<PAGE>   3

    4. Intellectual Property. Promisor recognizes and agrees that, on and after
the date hereof, Promisor will not have the right to use for Promisor's own
account any of the service marks, trademarks, trade names, licenses, procedures,
processes, labels, trade secrets or customer lists owned by or licensed to the
Company.

    5. Validity. To the extent permitted by applicable law, if it should ever be
held that any provision contained herein does not contain reasonable limitations
as to time, geographical area or scope of activity to be restrained, then the
court so holding shall at the request of Buyer or the Company reform such
provisions to the extent necessary to cause them to contain reasonable
limitations as to time, geographical area and scope of activity to be restrained
and to give the maximum permissible effect to the intentions of the parties as
set forth herein; and the court shall enforce such provisions as so reformed.
If, notwithstanding the foregoing, any provision hereof is held to be illegal,
invalid or unenforceable under present or future laws effective during the term
hereof, such provision shall be fully severable; this Agreement shall be
construed and enforced as if such illegal, invalid or unenforceable provision
had never comprised a part hereof; and the remaining provisions hereof shall
remain in full force and effect and shall not be affected by the illegal,
invalid or enforceable provision or by its severance here from. Furthermore, in
lieu of such illegal, invalid or unenforceable provision there shall be added
automatically by Buyer or the Company as a part hereof a provision as similar in
terms to such illegal, invalid or unenforceable provision as may be possible and
be legal, valid and enforceable, and the parties hereby agree to such provision.

    6. Notice. Any notice, request, instruction, document or other communication
to be given hereunder by any party hereto to any other party hereto shall be in
writing and validly given if (i) delivered personally, (ii) sent by telecopy
