Dear Creditor:

         At a special shareholders meeting held on March 27, 2001, 3dfx's
shareholders approved proposals to liquidate, wind up and dissolve 3dfx
Interactive, Inc. ("3dfx") pursuant to a plan of dissolution and to sell some of
3dfx's assets to an affiliate of NVIDIA Corporation ("NVIDIA") pursuant to an
asset purchase agreement (the "NVIDIA Sale").

         AS REQUIRED BY CALIFORNIA LAW, 3dfx IS HEREBY NOTIFYING YOU THAT IT HAS
ELECTED TO WIND UP ITS AFFAIRS AND VOLUNTARILY DISSOLVE IN ACCORDANCE WITH
CHAPTER 19 OF THE CALIFORNIA GENERAL CORPORATION LAW, AND IS NOW IN THE PROCESS
OF WINDING UP ITS AFFAIRS IN THE MANNER REQUIRED BY LAW AND AS PRESCRIBED UNDER
THE PLAN OF DISSOLUTION.

         3dfx recently made initial payments to creditors who chose to sign the
Terms of Settlement and Release sent to creditors in February 2001. The final
payment will be made to them as soon as 3dfx receives up to an additional $25
million from nVidia. In order to receive this additional payment, 3dfx must
certify to nVidia that it will be able to satisfy all its liabilities upon
receipt of the additional payment. To do this we resolve several items in
litigation, terminate a number of long term real estate leases, and dispose of
our subsidiaries in Northern Ireland and Mexico. We cannot estimate if or when
this may occur. Some creditors asked us to pay a higher amount than that offered
in exchange for an immediate full settlement. We offered to pay 70% of the total
owed for a full release to those creditors who did not wish to wait for the
final payment in full. We want to extend this same offer to our other creditors.

         Our records reflect that 3dfx owes you an aggregate amount of
$_____________ (the "Amount Owed"), which is the principal amount owed for goods
and services provided by you, but does not include any interest, penalties,
costs or attorney's fees. If you agree that this is the amount owed to you, then
you should review the "Full and Final Release and Settlement" attached, and if
it is acceptable to you, countersign it and return it to the address indicated
below and you will receive an immediate and final payment for 70% of the Amount
Owed, or $__________ (the "Final Settlement Amount"). We will cut and mail
checks to creditors who sign this agreement on the Friday following receipt of
the signed Full and Final Release and Settlement. If you do not agree that the
Amount Owed is correct, please let us know so that we may make the necessary
adjustments to the records so that they are in agreement and we can prepare a
corrected .

         If you agree to accept immediate payment of the Final Settlement Amount
as the final and total amount to be paid you by 3dfx and its subsidiaries, then
please read the following Full and Final Release and Settlement carefully,
countersign and return it to 3dfx at:

                             3DFX INTERACTIVE, INC.
                                  P.O. Box 790
                          Alviso, California 95002-0790

                      FULL AND FINAL RELEASE AND SETTLEMENT

                  The undersigned creditor ("Creditor"), on its own behalf and
         on behalf of its subsidiaries, affiliates, predecessors and successors
         (together, the "Releasing Parties"), agrees to accept $ _________ (the
         "Final Settlement Amount") in full, final, and complete satisfaction of
         all past, present or future claims of the Releasing Parties against
         3dfx Interactive, Inc. ("3dfx") and its subsidiaries, affiliates,
         predecessors, successors, officers, directors, employees, agents, and
         attorneys (together, the "Released Parties"), whether known or unknown,
         asserted or unasserted, and waives and releases any and all related
         claims including claims for penalties, interest, costs, disbursements
         or attorneys fees related in any way to the claims of the Releasing
         Parties against the Released Parties. The Releasing Parties acknowledge
         that they have had the opportunity to be advised by legal counsel, and
         that they are familiar with the provisions of the California Civil Code
         Section 1542 which provides as follows:

              A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR
              DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF
              EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY
              AFFECTED HIS SETTLEMENT WITH THE DEBTOR.

         The Releasing Parties, being aware of the above Code Section, hereby
         expressly, knowingly and intentionally waive any rights any of them may
         have thereunder, as well as under any other statute or common law
         principles of similar effect and agree that this Full and Final Release
         and Settlement expressly supersedes any and all prior written or oral
         agreements with any of the Released Parties.

         AS YOUR AGREEMENT WITH THE TERMS OF THIS FULL AND FINAL RELEASE AND
SETTLEMENT ABOVE MAY COMPROMISE THE AMOUNT YOU BELIEVE THAT 3dfx OWES TO YOU,
YOU ARE URGED TO CONSULT WITH AN ATTORNEY OF YOUR CHOICE TO ADVISE YOU OF THE
EFFECT OF YOUR EXECUTION OF THIS FULL AND FINAL RELEASE AND SETTLEMENT.

THE UNDERSIGNED CREDITOR OF 3dfx INTERACTIVE, INC. AND/OR ONE OR MORE OF ITS
SUBSIDIARIES (INCLUDING STB SYSTEMS, INC.) DOES HEREBY ACKNOWLEDGE AND AGREE TO
ALL OF THE TERMS SET FORTH IN THIS FULL AND FINAL RELEASE AND SETTLEMENT.

("CREDITOR" OR "YOU")

Dear Creditor:

         I am enclosing for your information a copy of the Prospectus/Proxy
Statement that is being distributed to the shareholders of 3dfx Interactive,
Inc. ("3dfx"). The Prospectus/Proxy Statement describes the proposals that are
being submitted for 3dfx shareholder approval, namely the dissolution of 3dfx
and the sale to an affiliate of Nvidia Corporation ("Nvidia") of certain assets
of 3dfx (the "Nvidia Sale"). The SEC decided not to review the Prospectus/Proxy
Statement and has since declared the related registration statement effective,
which allowed us to accelerate the 3dfx shareholder meeting date to vote on
these proposals to March 27, 2001.

         Under the terms of the Asset Purchase Agreement between 3dfx and
Nvidia, Nvidia has agreed to pay $70 million in cash and one million shares of
Nvidia common stock for the 3dfx assets that it is purchasing, subject to a
number of conditions. Of the $70 million in cash to be received by 3dfx at
closing, $15 million must immediately be applied to the repayment of a bridge
loan made by Nvidia to 3dfx in December 2000, so 3dfx will receive a net cash
amount at closing of $55 million (the "Closing Cash Payment"). Nvidia is not,
however, required to deliver the shares of its common stock provided for in the
purchase agreement (the "Stock Payment") until 3dfx is able to satisfy certain
additional conditions, including 3dfx's delivery of a certificate that it has
satisfied all of its and its subsidiaries' liabilities. In order to meet this
post-closing requirement, 3dfx is permitted under the terms of the purchase
agreement to request that Nvidia make a one-time exchange of up to 500,000
shares of Nvidia common stock from the Stock Payment for up to $25 million in
cash, provided that the cash from the exchange will be sufficient to satisfy in
full all remaining liabilities.

         As the Closing Cash Payment will not alone be sufficient to satisfy
3dfx's and its subsidiaries' liabilities, 3dfx expects that it will be required
to exchange stock for cash from Nvidia in order to fully pay these liabilities
and otherwise be entitled to receive the balance of the Stock Payment. 3dfx
expects that the aggregate cash provided by the Closing Cash Payment and the
stock-for-cash exchange will be sufficient to pay all known current and
determinable liabilities, although unknown, contingent or disputed liabilities
could result in liabilities exceeding this aggregate cash amount. If this were
to be the case, then Nvidia would not be obligated to make the stock-for-cash
exchange or otherwise deliver the Stock Payment to 3dfx.

         We have updated 3dfx's accounts payable records in response to the
helpful feedback we received from a number of creditors. Our records reflect
that 3dfx owes you an aggregate amount of $_____________ (the "Repayment
Amount"), which is the principal amount owed for goods and services provided by
you, but does not include any interest, penalties, costs or attorney's fees
(other than interest accruing on loans extended by financial institutions). If
you agree that this is the amount owed to you, then 3dfx is requesting that you
review the "Terms of Settlement and Release" set forth below in this letter,
countersign it and return it to the address indicated below. 3dfx is sending
this letter to you and to all of its other creditors and is seeking
counter-execution of these letters for three principal reasons:

         o        First, to ensure to the greatest extent possible that all of
                  3dfx's creditors are treated fairly and equally by receiving
                  the principal amounts of their claims;

         o        Second, to assure Nvidia that 3dfx will, upon making the
                  stock-for-cash exchange, be in a position to satisfy all of
                  its liabilities; and

         o        Third, to ensure that amounts owed by 3dfx to its creditors
                  are paid as soon as possible, without delay resulting from
                  resolving contingent or disputed claims.

         UPON CLOSING OF THE NVIDIA SALE, A PORTION OF THE CLOSING CASH PAYMENT
WILL BE RESERVED TO FINANCE THE WIND-DOWN OF 3DFX'S OPERATIONS, WITH THE BALANCE
USED TO MAKE PRO RATA PAYMENTS TO ALL 3DFX CREDITORS WHOSE COUNTERSIGNED LETTERS
ARE TIMELY RECEIVED BY 3DFX. THE BALANCE OF THE REPAYMENT AMOUNT DUE TO SUCH
CREDITORS WILL BE PAID TO THEM FOLLOWING THE STOCK-FOR-CASH EXCHANGE PROVIDED
FOR IN THE PURCHASE AGREEMENT WITH NVIDIA. THOSE CREDITORS WHOSE COUNTERSIGNED
LETTERS ARE NOT TIMELY RECEIVED BY 3DFX WILL NOT RECEIVE PAYMENT OF THEIR CLAIM
UNTIL ALL CLAIMS ARE RESOLVED AND 3DFX RECEIVES SUFFICIENT CASH TO PAY ALL
CREDITORS IN FULL.

         If you are in agreement that the Repayment Amount indicated above is
the total amount owed to you by 3dfx and its subsidiaries, then please read the
following Terms of Settlement and Release carefully, countersign this letter and
return it to 3dfx as indicated below:

                         TERMS OF SETTLEMENT AND RELEASE

                  Creditor, on its own behalf and on behalf of its subsidiaries,
         affiliates, predecessors and successors (together, the "Releasing
         Parties"), agrees to accept the Repayment Amount indicated above in
         this letter in full, final, and complete satisfaction of all of the
         claims of the Releasing Parties against 3dfx and its subsidiaries,
         affiliates, predecessors, successors, officers, directors, employees,
         agents, and attorneys (together, the "Released Parties"), whether known
         or unknown, asserted or unasserted, from the beginning of time to
         February 16, 2001, and waive and release any and all related claims
         including claims for penalties, interest, costs, disbursements or
         attorneys fees related in any way to the claims of the Releasing
         Parties against the Released Parties. The Releasing Parties acknowledge
         that they have had the opportunity to be advised by legal counsel, and
         that they are familiar with the provisions of the California Civil Code
         Section 1542 which provides as follows:

              A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR
              DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF
              EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY
              AFFECTED HIS SETTLEMENT WITH THE DEBTOR.

         The Releasing Parties, being aware of the above Code Section, hereby
         expressly, knowingly and intentionally waive any rights any of them may
         have thereunder, as well as under any other statute or common law
         principles of similar effect.

         It is understood and agreed that if on or before May 18, 2001, you do
not receive a pro rata payment of that portion of the Closing Cash Payment
allocated to 3dfx creditors whose countersigned letters are received by 3dfx,
then all the terms of this letter, including the Terms of Settlement and
Release, shall be null and void.

         BECAUSE YOUR AGREEMENT WITH THE TERMS OF THIS LETTER, INCLUDING THE
TERMS OF SETTLEMENT AND RELEASE ABOVE, MAY COMPROMISE THE AMOUNT YOU BELIEVE
THAT 3DFX OWES TO YOU, YOU ARE URGED TO CONSULT WITH AN ATTORNEY OF YOUR CHOICE
TO ADVISE YOU OF THE EFFECT OF YOUR COUNTER-EXECUTION OF THIS LETTER.

         If you are in agreement with all of the terms of this letter, including
the above Terms of Settlement and Release, please countersign this letter in the
space provided below and return this letter so that it is received by 3dfx on or
before March 23, 2001 at the following address:

                             3DFX INTERACTIVE, INC.
                                  P.O. Box 790
                          Alviso, California 95002-0790

         If you have any questions regarding the Nvidia Sale or the process by
which 3dfx intends to address the claims of its creditors, please address them
to me at the above address. I assure you that it is 3dfx's intent to treat all
of its creditors fairly and equally. Please know that I, on behalf of 3dfx, very
much appreciate the patience that you and other 3dfx creditors have demonstrated
to this point. As you can see, the terms and procedures leading up to the
closing of the Nvidia Sale, as well as winding up of 3dfx's affairs thereafter,
are delicate and complex. I sincerely believe that your continued cooperation
with this process is not only in your best interest, but in the best interest of
all of 3dfx's creditors. I look forward to receiving your countersigned copy of
this letter.

                              Sincerely,

                              Richard A. Heddleson
