ITEM 1.  FINANCIAL STATEMENTS

         The unaudited, condensed financial statements included herein,
commencing at page F-1, have been prepared in accordance with the requirements
of Regulation S-B and supplementary financial information included herein, if
any, has been prepared in accordance with Item 310(b) of Regulation S-B and,

included in financial statements prepared in accordance with generally accepted
accounting principles. In the opinion of management, all adjustments (consisting
only of normal recurring accruals) necessary for a fair presentation of the
financial information for the interim periods reported have been made. Results
of operations for the three month ended March 31, 1998 are not necessarily
indicative of the results for the year ending December 31, 1998.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

         Orthodontix, Inc. (f/k/a Embassy Acquisition Corp. (the "Company") was
formed in November 1995 to seek to effect a merger, exchange of capital stock,
asset acquisition or similar business combination (a "Business Combination")
with an acquired business (an "Acquired Business"). In connection with its
initial capitalization, the Company issued an aggregate of 1,160,000 shares of
Common Stock to its officers, directors, and other shareholders for an aggregate
sum of $76,078. On April 2, 1996, the Company's Registration Statement on Form
SB-2 (the "Registration Statement") was declared effective by the U.S.
Securities and Exchange Commission (the "SEC"). Pursuant to the Registration
Statement, the Company, in its initial public offering of securities, offered
and sold 1,380,000 shares of Common Stock, par value $.0001 per share, at a
purchase price of $6.00 per share (the "Offering") and received net proceeds of
approximately $7,052,300 after the payment of all expenses of the Offering (the
"Net Proceeds"). In addition, the Company issued Underwriter Options to purchase
120,000 shares of Common Stock. The Offering was a "blank check" offering.

         On May 6, 1997, the Company entered into a Letter of Intent with
Orthodontix Subsidiary, Inc.(f/k/a Orthodontix, Inc. (the "Letter of Intent") a
Florida corporation ("Orthodontix"), regarding a business combination of the
Company or its wholly-owned subsidiary and Orthodontix, Inc. (the
"Transaction"). Orthodontix had conducted no operations as of such date other
than in connection with its agreements in principle to acquire certain assets,
assume certain liabilities, and provide long-term management services to certain
orthodontic practices (the "Practices") in exchange for cash and shares of
common stock (the "Practice Acquisitions").

         On August 29, 1997, the Company and Orthodontix amended the terms of
the Letter of Intent to provide that either party could terminate the Letter of
Intent if a definitive agreement had not been executed by October 30, 1997. The
Letter of Intent had previously provided that either


                                       1


<PAGE>   5


party could terminate the Letter of Intent if a definitive agreement regarding
the Transaction had not been executed by August 30, 1997.

         As of October 30, 1997, the Company and Orthodontix entered into an
Agreement and Plan of Merger and Reorganization (the "Agreement") regarding the
Transaction. Pursuant to the Agreement, the parties would engage in the
Transaction, which at the closing of the Transaction (the "Closing") would
result in Orthodontix becoming a wholly-owned subsidiary corporation of the
Company in exchange for that number of shares of Common Stock of the Company
(the "Merger Stock") representing approximately 56% of the Company's outstanding
shares of Common Stock after giving effect to the Transaction but without giving
effect to any options or warrants to acquire shares of Common Stock which are
contemplated to be outstanding at the Closing. The actual number of shares to be
issued in connection with the Transaction was subject, in part, to the average
of the closing bid and ask price, as reported on the OTC Electronic Bulletin
Board or similar quotation board of the Company's shares of Common Stock for the
15 trading days immediately preceding the date of the Closing (the "Share
Value").

         On April 16, 1998, the Company consummated the Transaction pursuant to
the Agreement. At the closing of the Transaction, (i) Orthodontix became a
wholly-owned subsidiary of the Company in exchange for, among other things,
3,374,637 shares of the Company's Common Stock, representing approximately 57.1%
of the Company's outstanding Common Stock after giving effect to the
Transaction; and (ii) the Company changed its name to "Orthodontix, Inc." The
Company's Registration Statement on Form S-4, as amended (SEC File No.
333-48677), relating to the Transaction is incorporated by reference herein.

Liquidity and Capital Resources/Plan of Operation

         As of March 31, 1998 and December 31, 1997, the Company had cash and
cash equivalents of $475,751 and $547,939, respectively, and restricted cash and
cash equivalents of $6,955,040 and $6,878,156, respectively. As of March 31,
1998 and December 31, 1997, the Company had total liabilities of $70,910 and
$88,850, respectively, and common stock subject to redemption of $7,401,103 and
$7,378,467, respectively. 90% of the Net Proceeds ($6,346,800) (the "Escrow
Fund") were delivered to Fiduciary Trust International of the South, as Escrow
Agent, to be held in escrow by such firm, until the earlier of (i) written
notification by the Company of its need for all or substantially all of the
Escrow Fund for the purpose of implementing a Business Combination; or (ii) the
exercise by certain shareholders of the Redemption Offer (as defined in the
Registration Statement). As of March 31, 1998, there was $6,955,040 (at market
value) in the Escrow Fund. The Escrow Fund is currently invested in United
States government-backed short-term securities.

         Other than the Escrow Fund, the Company, as of March 31, 1998, had
$475,751 and cash equivalents all of which was received from the initial
capitalization and the Offering (other than


                                       2


<PAGE>   6


interest income earned thereon) (the "Operating Funds"). The Company believes
the Operating Funds will be sufficient for its cash requirements for at least
the next twelve months.

         For the three month period ended March 31, 1998, the Company incurred
$49,265 of operating expenses and derived interest income of $83,561 as compared
with the three month period ended March 31, 1997, when the Company incurred
$12,323 of operating expenses and derived interest income of $81,245.

issued an aggregate of 3,374,637 shares of the Company's Common Stock (the
"Shares") and granted options to acquire an aggregate of 956,303 shares of
Common Stock (the "Options"), of which options to acquire 537,500 shares are
currently exercisable. The Shares were issued in a transaction registered on the
Company's Registration Statement on Form S-4 declared effective by the
Securities and Exchange Commission on March 26, 1998. The Company relied upon
the exemption in Section 4(2) of the Securities Act of 1933 in connection with
the issuance of the Options.

(1) BASIS OF PRESENTATION:

The accompanying interim financial statements presented herein do not include
all disclosures provided in the annual financial statements. These unaudited
financial statements should be read in conjunction with the annual financial
statements and the footnotes for the fiscal year ended on December 31, 1997
thereto contained in the Form 10-KSB of Embassy Acquisition Corp. (the
"Company") as filed with the U.S. Securities and Exchange Commission on March

In the opinion of the Company, the accompanying unaudited financial statements
contain all adjustments, which are of a normal recurring nature, necessary for a
fair presentation of the financial statements. The results of operations for the
three months ending March 31, 1998 are not necessarily indicative of the results

Proceeds totaled $7,053,700, which was net of $1,226,300 in underwriting and

purchase options ("the "Underwriter Options") to purchase up to 120,000 shares
of the Company's common stock at an exercise price of $7.80 per share. The
Underwriter Options will be exercisable for a period of five years from the
effective date of the Company's Registration Statement. The Company has also
agreed to certain registration rights with respect to the shares underlying the
Underwriter Options.

In accordance with the Offering, 90% of the net proceeds therefrom were placed

(2) ORGANIZATION (CONTINUED):

written notification by the Company of its need for all or substantially all of
the Escrow Fund for the purpose of implementing a business combination, (ii) the
exercise by certain shareholders of the Redemption Offer, as defined, or (iii)
the expiration of no more than 30 months from the date of the Offering. Amounts
in the Escrow Fund, including interest earned thereon, are prohibited from being
used for any purpose other that a business combination. Such amounts are
included in restricted cash and cash equivalents at March 31, 1998.

In the event the Company does not successfully effect a business combination
within 24 months (or in certain circumstances 30 months) from the date of the
consummation of the Offering, the Company will submit a proposal to liquidate
the Company. If such proposal is approved, the Company will distribute the
Company's Liquidation Value, as defined, to the Public Stockholders. Since the
Company may be required to refund all available equity to the Public
Shareholders, such amounts have been classified in the accompanying balance
sheet as common stock subject to redemption. Periodic changes in the Liquidation
Value are reflected as adjustments to stockholders' equity.

(3) NET INCOME PER COMMON AND COMMON EQUIVALENT SHARE:

The calculation of basic and diluted net income per share for the three months
ended March 31, 1998 and 1997 are as follows:

   (1) Warrants to purchase 120,000 shares of common stock were not included in
computation of diluted net income per share for 1997 since warrants exercise
price was greater than the average price of the underlying common shares.

(4) SUBSEQUENT EVENT:

On May 6, 1997, the Company (Embassy Acquisition Corp.) entered into a Letter of
Intent with Orthodontix, Inc. ("Orthodontix"), a Florida corporation, regarding
a business combination of the Company or its wholly-owned subsidiary and
Orthodontix (the "Transaction"). Orthodontix had conducted no operations as of
such date other than in connection with its agreements in principle to acquire
certain assets, assume certain liabilities and provide long-term management
services to certain orthodontic practices (the "Practices").

As of October 30, 1997, the Company and Orthodontix entered into an Agreement
and Plan of Merger and Reorganization (the "Agreement") regarding the
Transaction. Pursuant to the Agreement, the parties would engage in the
Transaction, which at the closing of the Transaction (the "Closing") would
result in Orthodontix becoming a wholly-owned subsidiary corporation of the
Company in exchange for that number of shares of Common Stock of the Company
(the "Merger Stock") representing approximately 56% of the Company's outstanding
shares of Common Stock after giving effect to the transaction but without giving
effect to any options or warrants to acquire shares of Common Stock which are

contemplated to be outstanding at the Closing. The actual number of shares to be
issued in connection with the transaction was subject, in part, to the average
of the closing bid and ask price, as reported on the OTC Electronic Bulletin
Board or similar quotation board of the Company's shares of Common Stock for the
last 15 trading days immediately preceding the date of the Closing (the "Share
Value").

On April 16, 1998, the Company consummated the transaction pursuant to the
Agreement. At the Closing (i) Orthodontix became a wholly-owned subsidiary of
the Company in exchange for, among other things, 3,374,637 shares of the
Company's Common Stock, representing approximately 57.1% of the Company's
outstanding Common Stock after giving effect to the transaction; and (ii) the
Company changed its name to "Orthodontix, Inc."
