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

         On January 13, 1998, Lone Star purchased (i) 1,400,000 shares of
Greenbriar's Series F Senior Convertible Preferred Stock (the "Series F
Preferred"), $0.10 par value per share, at a purchase price of $10.00 per share
and (ii) 800,000 shares of Greenbriar's Series G Senior Non-Voting Convertible
Preferred Stock $0.10 par value per share (the "Series G Preferred"), at a
purchase price of $10.00 per share. The Series F Preferred and Series G
Preferred (collectively, the "Preferred Stock") were convertible, subject to the
terms of the Preferred Stock, into shares of Common Stock, based on a conversion
price of $17.50 per share of Common Stock. The aggregate purchase price for the
Preferred Stock was $22,000,000 and was funded by capital contributions from
Lone Star's partners. Lone Star assigned the Preferred Stock to LSOF Greenbriar,
L.L.C., a Delaware limited liability and wholly owned subsidiary of Lone Star
("LSOF Greenbriar"), pursuant to an Assignment and Assumption Agreement dated
January 13, 1998. On July 23, 1998, LSOF Greenbriar assigned the Preferred Stock
to Pooled Equity.

         The terms of the Preferred Stock are set forth in (i) the Stock
Purchase Agreement dated as of December 31, 1997 between Greenbriar and Lone
Star filed as Exhibit 1 (the "Stock Purchase Agreement"), (ii) the Certificate
of Voting Powers, Designations, Preferences and Relative, Participating,
Optional or other Special Rights of Series F Senior Convertible Preferred Stock
filed as Exhibit 2 (the "Series F Certificate of Designation") and (iii) the
Certificate of Voting Powers, Designations, Preferences and Relative,
Participating, Optional or Other Special Rights of Series G Senior Non-Voting
Convertible Preferred Stock filed as Exhibit 3 (the "Series G Certificate of
Designation," and together with the Series F Certificate of Designation, the
"Certificates of Designation").

         On February 1, 2000 Greenbriar redeemed 189,381 shares of Series G
Preferred owned directly by Pooled Equity for an aggregate price of $2,500,000,
which equals a price of $13.20 per share. Such redemption was pursuant to a
letter agreement between LSOF Greenbriar and Greenbriar dated January 31, 2000
(the "First Letter Agreement"), filed as Exhibit 6, whereby Greenbriar agreed to
use all proceeds, after payment of reasonable out-of-pocket expenses, from the
sale or refinancing of capital assets to redeem shares of Preferred Stock. On
March 1, 2000, LSOF Greenbriar assigned all of its rights in such letter
agreement to Pooled Equity pursuant to an Assignment of Rights filed as Exhibit
8 (the "Assignment of Rights").

         On February 4, 2000, Greenbriar redeemed 75,722 shares of Series G
Preferred owned directly by Pooled Equity for an aggregate price of $1,000,000,
which equals a price of $13.20 per share. Such redemption was pursuant to a
letter agreement between LSOF Greenbriar and Greenbriar dated February 4, 2000
filed as Exhibit 7. On March 1, 2000, LSOF Greenbriar assigned all of its rights
in such letter agreement to Pooled Equity pursuant to the Assignment of Rights.

- -----------------------------------------------------------------------------

         On April 14, 2000 Greenbriar redeemed 37,200 shares of Series G
Preferred owned directly by Pooled Equity for an aggregate price of $500,000,
which equals a price of $13.44 per share. Such redemption was pursuant to a
letter agreement between Pooled Equity and Greenbriar dated April 14, 2000 filed
as Exhibit 9. 2

         While conducting due diligence in response to certain discussions with
Greenbriar to modify and/or extend certain provisions of the Certificates of
Designation, Pooled Equity learned and verified through review of Greenbriar's
corporate records that, since the date of issuance of the Series F Preferred and
the Series G Preferred, Greenbriar had issued (the "Option Issuances") various
options (each a "Stock Option") to purchase shares of Common Stock to certain
employees, officers and directors of Greenbriar for a consideration per share
that was less than the conversion price of the Series F Preferred and the Series
G Preferred. Greenbriar failed to provide written notice to Pooled Equity, its
affiliates or its representatives of these issuances, as required by the terms
of the Certificates of Designation. These Option Issuances triggered the
antidilution provisions under the Certificates of Designation, which provisions
provide that the conversion price for the Preferred Stock shall be adjusted
downward so that the conversion price is equivalent to the lowest exercise price
per share of Common Stock with respect to these Option Issuances. The lowest
exercise price for any Stock Option issued by Greenbriar was $0.69 per share of
Common Stock. Consequently, the conversion price for the Series F Preferred and
the Series G Preferred was automatically (and without further action on the part
of Greenbriar or Pooled Equity) adjusted downward from $17.50 per share of
Common Stock to $0.69 per share of Common Stock. As a result, each share of
Preferred Stock, which had a liquidation preference of $10.00 per share, has
become convertible into approximately 14.49 shares of Common Stock.

         On October 26, 2000, Terlingua purchased 2,200 shares (the "Terlingua
Shares") of Common Stock on the open market for a purchase price of $0.75 per
share. The aggregate purchase price for the Terlingua Shares was $1650.00 and
was funded from working capital of Terlingua.

         On October 30, 2000, Pooled Equity delivered to Greenbriar a written
Notice of Conversion (the "Conversion Notice"), filed as Exhibit 10, whereby
Pooled Equity elected to convert the (i) 1,400,000 shares of Series F Preferred
and (ii) 497,697 shares of Series G Preferred owned by it (a total of 1,897,697
shares of Preferred Stock) into 27,502,855 shares of Common Stock.3 The
Conversion Notice directed Greenbriar to immediately issue to Pooled Equity the
lesser of (i) 6,955,135 shares of Common Stock and (ii) such number of shares of
Common Stock that would equal 49.8% of the outstanding Common Stock. The
Conversion Notice also directed Greenbriar to issue the remaining shares (the
"Remaining Common Shares") of Common Stock due to Pooled Equity as a result of
the conversion of the Preferred Stock upon written notice from Pooled Equity
that the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act
of 1976 had expired or terminated (or such act was no longer applicable) with
respect the conversion of the Preferred Stock.

         On October 31, 2000, Greenbriar notified Pooled Equity that, in
Greenbriar's opinion, the Conversion Notice may be invalid and/or that Pooled
Equity may not have perfected its conversion rights with respect to the
Preferred Stock.

- ----------
2 At the hearing held on March 29, 2001, described below, Pooled Equity agreed
that Greenbriar had redeemed an additional 1,897 shares of Series G Preferred on
April 14, 2000, and that the correct number of shares of Common Stock to be
issued to Pooled Equity as of October 30, 2000, was 27,475,362.

3 At the hearing held on March 29, 2001, described below, Pooled Equity agreed
that Greenbriar had redeemed an additional 1,897 shares of Series G Preferred on
April 14, 2000, and that the correct number of shares of Common Stock to be
issued to Pooled Equity as of October 30, 2000, was 27,475,362.

- -----------------------------------------------------------------------------

         In response to Greenbriar's allegation that the Conversion Notice may
be invalid and/or that Pooled Equity may not have perfected its conversion
rights with respect to the Preferred Stock, on November 3, 2000, Pooled Equity
filed a petition (the "Petition") in State District Court in Dallas County,
Texas (the "District Court") seeking a judgment declaring that the Conversion
Notice is valid and effective as of October 30, 2000 and that it is entitled to
convert the Preferred Stock into Common Stock at a price of $0.69 per share of
Common Stock. Additionally, Pooled Equity sought a permanent injunction barring
Greenbriar from taking any action that would impair or prejudice Pooled Equity's
rights in the Preferred Stock and Common Stock. A copy of the Petition has been
filed as Exhibit 11.

         On November 20, 2000, Greenbriar filed its Original Answer and
Counterclaim (the "Answer") denying the allegations contained in the Petition
and alleged by counterclaim (the "Counterclaim") that Pooled Equity breached an
agreement with Greenbriar regarding Greenbriar's sale of assets necessary to
redeem the Preferred Stock. Pooled Equity will vigorously defend the
Counterclaim. A copy of the Answer has been filed as Exhibit 12.

         On December 5, 2000, Pooled Equity delivered a Notice of Default
("Notice of Default") to Greenbriar notifying Greenbriar that it was in breach
of Section 6.26 of the Stock Purchase Agreement for failure to comply with the
Conversion Notice. A copy of the Notice of Default has been filed as Exhibit 13.

         On December 5, 2000, Pooled Equity also delivered a letter (the "Make
Whole Letter") notifying Greenbriar that Pooled Equity was demanding payment of
$8,587,059 (the "Make Whole Amount"). Pursuant to that certain Agreement (the
"Make Whole Agreement"), dated as of December 31, 1997, by and between
Greenbriar and Lone Star, the Make Whole Amount became due on the tenth business
day after the date on which all of the Preferred Stock was converted into shares
of Common Stock. A copy of the Make Whole Agreement has been filed as Exhibit
14.

         On December 11, 2000, Pooled Equity filed a Demand for Arbitration
Before the American Arbitration Association (the "Arbitration Demand") seeking
to consolidate and enforce its claims contained in the Petition, the Notice of
Default and the Make Whole Letter. Pooled Equity's claims under the Stock
Purchase Agreement and the Make Whole Agreement require all disputes arising
thereunder to be resolved by arbitration with the American Arbitration
Association. On January 5, 2001, Greenbriar filed a Motion to Stay Arbitration
(the "Motion to Stay") with the District Court. As of the date hereof, the
District Court has not ruled on the Arbitration Demand or the Motion to Stay.

         On January 11, 2001, Pooled Equity made an application for a temporary
restraining order with the District Court to prevent the automatic conversion of
its Preferred Stock into Common Stock on January 13, 2001 in accordance with the
Certificates of Designation. The District Court denied Pooled Equity's
application for a temporary restraining order.

         On January 12, 2001, Pooled Equity delivered a Notice of Default (the
"Second Notice of Default") to Greenbriar notifying Greenbriar that Events of
Default have occurred under the covenants contained in Sections 6.8(e), 6.29,
6.30, 6.31, 6.32 and 6.33 of the Stock Purchase Agreement. As a result of such
Events of Default, Greenbriar owes Pooled Equity additional dividends of 12% per
annum and Pooled Equity may put the Preferred Stock to Greenbriar for 20% of
such Preferred Stock's liquidation value. In addition, interest on all unpaid
dividends is accruing at the rate of 12% per annum. As a result of Greenbriar's
failure to comply with the foregoing covenants, and its failure to pay such
accrued additional dividends for two consecutive quarters, Pooled Equity,
through its ownership of Series F Preferred, has the right to appoint 70% of the
Board of Directors membership of Greenbriar. All such remedies arose prior to
the mandatory conversion of the Preferred Stock described below. A copy of the
Second Notice of Default has been filed as Exhibit 15.

- -----------------------------------------------------------------------------

         On January 12, 2001, Pooled Equity also delivered a notice (the
"Observer Notice") to Greenbriar of Pooled Equity's exercise of its right, under
the Series F Certificate of Designation and the Stock Purchase Agreement, to
attend all Board of Directors meetings and any committees thereof. A copy of the
Observer Notice has been filed as Exhibit 16.

         On January 13, 2001, Greenbriar delivered notices (the "Mandatory
Conversion Notices") that pursuant to Section 6.3 of each of the Certificates of
Designation, Pooled Equity's 1,400,000 shares of Series F Preferred and 444,854
shares of Series G Preferred were automatically converted at a conversion price
of $17.50 per share of Common Stock into 800,000 and 254,202 shares of Common
Stock, respectively. In addition, Greenbriar notified Pooled Equity that, based
upon its records, Greenbriar owes Pooled Equity a total of $27,166,714 under the
Make Whole Agreement (the "Make Whole Payments"). Greenbriar further stated in
the Mandatory Conversion Notices that it was unable to make the Make Whole
Payments at this time but that it intended to do so pursuant to the terms of the
Make Whole Agreement and as permitted by Section 78.288 of the Nevada Revised
Statutes. Copies of the Mandatory Conversion Notices have been filed as Exhibits
17 and 18.

         On January 15, 2001, Pooled Equity delivered a letter to Greenbriar
responding to the Mandatory Notices (the "Mandatory Conversion Response
Letter"). Pooled Equity stated in the Mandatory Conversion Response Letter that:

         (i)      the proper conversion price for the Preferred Stock was $0.69
                  per share of Common Stock;

         (ii)     the number of shares of Series G Preferred owned by Pooled
                  Equity is 497,6974, not 444,854 as stated in the Mandatory
                  Conversion Notice;

         (iii)    Pooled Equity never agreed to the alleged redemption of 50,946
                  shares of Series G Preferred on December 20, 2000. The
                  proceeds of $760,000 received in such alleged redemption was
                  never discussed and it is Pooled Equity's view that such
                  amount should apply to amounts owing to Pooled Equity under
                  the Make Whole Amount; and

         (iv)     Greenbriar's calculation of the liquidation value of the
                  Preferred Stock failed to include penalty dividends accruing
                  since at least June 30, 2000, late interest on such dividends
                  accruing at 12% per annum and Pooled Equity's cost and
                  expenses payable pursuant to the Stock Purchase Agreement.

         A copy of the Mandatory Conversion Response Letter has been filed as
Exhibit 19.

         On February 8, 2001, Pooled Equity filed a Motion for Partial Summary
Judgment in District Court (the "Motion") seeking a judgment that (i) the
conversion price of the Preferred Stock was adjusted to $0.69 per share, the
lowest exercise price for the Stock Options; (ii) on October 30, 2000, Pooled
Equity properly exercised its right to convert the Preferred Stock at $0.69 per
share of Common Stock; and (iii) the conversion price of the Preferred Stock was
not readjusted due to any subsequent rescission of the Stock Options. A copy of
the Motion has been filed as Exhibit 20.

- ----------
4 At the hearing held on March 29, 2001, described below, Pooled Equity agreed
that Greenbriar had redeemed an additional 1,897 shares of Series G Preferred on
April 14, 2000, and that the correct number of shares of Common Stock to be
issued to Pooled Equity as of October 30, 2000, was 27,475,362.

- -----------------------------------------------------------------------------

         On March 29, 2001, the District Court held a hearing on Pooled Equity's
Motion. At the end of the hearing, the District Court granted Pooled Equity's
motion on all counts.

         On April 5, 2001, the District Court entered an order (the "Order")
granting the Motion. A copy of the Order has been filed as Exhibit 21.

         On August 1, 2001, Pooled Equity and Greenbriar entered into a Master
Settlement Agreement (the "Settlement"). A copy of the Settlement has been filed
as Exhibit 22. Under the terms of the Settlement, Greenbriar repurchased all of
Pooled Equity's ownership interests in Greenbriar, and Pooled Equity released
all claims in exchange for $4,000,000 in cash and the conveyance of 11 assisted
living properties (the "Properties") out of the 25 such properties owned and
operated by Greenbriar, subject to any indebtedness thereon. Upon such transfer
and pursuant to a mutual release, Greenbriar then released Pooled Equity from
all claims.

         In addition, in connection with the Settlement, certain stockholders of
Greenbriar entered into a consent agreement (the "Consent), pursuant to which
such holders consented to the Settlement and such holders gave Pooled Equity an
irrevocable proxy and power of attorney to vote their shares of Common Stock - a
total of 4,729,157 shares - with respect to any matter related to the Settlement
that was presented to Greenbriar's stockholders for a vote.

         A copy of the Consent, including a Form of Irrevocable Proxy and Power
of Attorney, has been filed as Exhibit 23.

         The transfer of nine of the Properties pursuant to the Settlement
occurred on October 3, 2001, and the transfer of one of the final two Properties
occurred on each of October 31, 2001, and March 5, 2002.

ITEM 4.  PURPOSE OF THE TRANSACTION.

         Except for the purchase of the Terlingua Shares, the transactions
described in Item 3 above occurred as a result of privately negotiated
transactions with Greenbriar. In each case, Lone Star acquired the Preferred
Stock and the Common Stock issuable upon conversion thereof, and Terlingua
acquired the Terlingua Shares, for investment purposes.

         As described above, upon closing the Settlement, Pooled Equity has
disposed of all of its shares of Common Stock. Terlingua, Hudson, Associates,
Advisors and Grayken continue to beneficially own 2,200 shares of Common Stock.

         Other than in connection with the Settlement, none of Pooled Equity,
Terlingua or any Control Person has any present plans or intentions which would
result in or relate to any of the transactions described in subparagraphs (a)
through (j) of Item 4 of Schedule 13D.

ITEM 5.    INTEREST IN SECURITIES OF THE ISSUER.

         Upon closing the Settlement on March 5, 2002, none of Pooled Equity,
GenPar, Lone Star, Partner or Management beneficially own any shares of Common
Stock and Terlingua, Hudson, Associates, Advisors and Grayken each, until such
shares are otherwise sold or transferred, beneficially own and have the sole
power to vote and dispose of 2,200 shares of Common Stock (approximately 0.03%
of the shares of Common Stock based on the information as to the number of
shares of Common Stock outstanding on August 14, 2001, as reported in
Greenbriar's Quarterly Report on Form 10-Q for the quarter ended June 30, 2001).
As of March 5, 2002, each of Pooled Equity, GenPar, Lone Star, Partner,
