ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

      Funds for the purchase of shares listed herein as beneficially owned by

purchase of other shares reported as beneficially owned by the Reporting
Entities were or will be provided from the assets of other funds for which the
Adviser acts as investment adviser.

ITEM 4. PURPOSE OF TRANSACTION.

      Seitel, Inc. emerged from bankruptcy proceedings on July 2, 2004. As part
of its new capitalization, Seitel registered (Registration No. 333-113446)
125,000,000 shares of new common stock (the "Common Stock") and 25,375,683
Common Stock purchase warrants (the "Purchase Warrants"), which were issued to
its stockholders of record as of June 25, 2004. Each of the Purchase Warrants is
exercisable, at 60 cents per share, for 4.926 shares of Common Stock, until they
expire on August 2, 2004.

      To ensure that the Company would realize gross proceeds of $75,000,000 to
the extent the Purchase Warrants are not exercised in full prior to August 2,
2004, Seitel entered into a Standby Funding Commitment Letter Agreement (the
"Standby Purchase Agreement"), dated as of January 5, 2004, with HBV Alternative
Strategies LLC (on behalf of the Fund and certain other funds and accounts
managed by the Adviser (the "Mellon entities")). Pursuant to the Standby
Purchase Agreement, the Mellon entities agreed to act as standby purchasers, and
in that capacity to purchase, after the Purchase Warrants expire on or prior to
August 12, 2004 (the "Guaranty Performance Date"), at 60 cents per share, all
shares of Common Stock not sold upon the exercise of the Purchase Warrants. If
none of the Purchase Warrants are exercised before they expire, the Mellon
entities would be required to purchase all 125,000,000 shares of Common Stock
for $75,000,000 in cash.

      In consideration for the standby purchase obligation, Seitel has agreed to
issue 15,037,568 additional warrants to the Mellon entities on the Guaranty
Performance Date (the "Standby Warrants"), which will be exercisable, at 72
cents per share (subject to adjustment upon the occurrence of certain events),
through July 2, 2011.

                                  Page 8 of 17


      Under the Standby Purchase Agreement, the Adviser also was granted the
right to designate 2 out of 7 directors to serve on reorganized Seitel's board
of directors. The Adviser has designated Messrs. Robert J. Simon and Robert
Kelley to serve on Seitel's board, effective as of July 2, 2004, when the
Company emerged from Chapter 11 bankruptcy proceedings. In addition, the Adviser
participated in the selection of a third director (together with the chairman of
the board and the official equity committee), Mr. Randell D. Stilley, to serve
as an initial director of Seitel.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

      The Reporting Entities currently have sole voting and dispositive power
with respect to 2,356,132 shares of Seitel Common Stock, of which 1,766,132
shares are held by the Fund and the remaining shares are held by other funds or
accounts for which the Adviser acts as investment adviser

      Pursuant to Seitel's Registration Statement and the aforementioned Standby
Purchase Agreement, the Reporting Entities may acquire an additional (1)
11,606,306 shares of Seitel Common Stock upon exercise of Purchase Warrants
(CUSIP NO. 816074140) issued to Mellon on July 2, 2004; (2) up to 113,393,694
shares of Seitel Common Stock on the Guaranty Performance Date; and (3) 15,
037,568 shares of Seitel Common Stock upon exercise of the Standby Warrants. Of
these, the Fund may acquire an additional (1) 8,699,966 shares of Common Stock
upon exercise of the Purchase Warrants, (2) up to 84,998,779 shares of Common
Stock on the Guaranty Performance Date and (3) 11,271,996 shares upon exercise
of the Standby Warrants.

      On July 2, 2004, Seitel issued to the Mellon entities 2,356,132 shares of
new Seitel Common Stock in exchange for previously held shares. In addition,
Mellon entities received 2,356,132 Purchase Warrants which, if exercised, would
enable them to acquire an additional 11,606,306 shares. If all the Purchase
Warrants issued to Mellon and the other shareholders of the Company were
exercised, the Reporting Entities' beneficial interest in Seitel's Common Stock
would remain at 9.28%. If none of the other shareholders exercise their Purchase
Warrants prior to their expiration on August 2, 2004, under the Standby Purchase
Agreement Mellon entities will be required to purchase an additional 113,393,694
shares of Seitel on the Guaranty Performance Date. However, even if Mellon
entities are not required by Seitel to purchase any additional shares of new
Seitel Common Stock under the Standby Purchase Agreement, Mellon entities will
receive additional Standby Warrants to purchase 15,037,568 shares (or, on a
fully diluted basis 9.10%) of Seitel Common Stock at an exercise price of 72
cents per share (subject to adjustment in certain circumstances).

      The percentages reported herein assume exercise by the Reporting Entities
of the Purchase Warrants and the Standby Warrants issued to them, but no
exercise by any other holder of the Purchase Warrants.

ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO
SECURITIES OF THE ISSUER

      Under the Standby Purchase Agreement, Mellon entities are entitled to
certain registration rights with respect to the Seitel Common Stock and Standby
Warrants. On July 2, 2004, Seitel entered into a registration rights agreement
(the "RRA") with Mellon granting Mellon entities two demand registration rights
and unlimited piggy-back registration rights to

                                     Page 9 of 17


enable them to resell all of the Common Stock and Standby Warrants issued to
them. A copy of the RRA is incorporated herein by reference as Exhibit 2.
