                                     PART I

ITEM 1.  BUSINESS

         Healthcare Acquisition Corp. ("Company") was formed in March 1995 as a
Specified Purpose Acquisition Company ("SPAC"), the objective of which is to
acquire an operating business ("Target Business") in the healthcare industry
("Healthcare Industry"). To date, the Company's efforts have been limited to
organizational activities, completion of its initial public offering and
evaluating potential Target Businesses and negotiating a possible Business
Combination (as hereinafter defined) and preparing and filing a proxy
statement/S-4 registration statement with the Securities and Exchange Commission
with respect to a potential Business Combination.

         On November 12, 1996, the Company, Healthcare Acquisition Inc., a Texas
corporation ("Acquisition") which is a wholly owned subsidiary of the Company,
and Encore Orthopedics, Inc., a Texas corporation ("Encore"), entered into an
Agreement and Plan of Merger ("Merger Agreement") dated November 12, 1996,
pursuant to which Acquisition will merge with and into Encore (the "Merger"),
and whereby Encore will be the surviving corporation and become a wholly-owned
subsidiary of the Company, subject to the terms and conditions of the Merger
Agreement. The Company has filed a Joint Proxy Statement/Registration Statement
on Form S-4 (Registration No. 333-22053) with the Securities and Exchange
Commission with respect to the proposed Merger which was declared effective by
the Securities and Exchange Commission on February 25, 1997 (the "Registration
Statement"). Meetings of the stockholders of the Company and Encore have been
called for March 25, 1997 to vote on the Merger. At such meeting, the
stockholders of the Company will also vote on certain amendments to the
Company's certificate of incorporation and the adoption of a Stock Option Plan
all as more fully disclosed in the Registration Statement.

         For a description of the primary attributes of a SPAC, please see the
section of the Registration Statement entitled "Business of HCAC" the provisions
of which are hereby incorporated by this reference into this Report on Form
10-K.

ITEM 2.  PROPERTIES

         The Company does not lease any permanent office space. However, it does
pay an administrative services fee to its legal counsel for the periodic use of
office space and secretarial and other basis office services. If the Merger is
consummated, the Company will discontinue its use of such offices and its
utilization of such services and conduct its activities from the current offices
of Encore.

         20,000 shares owned by the Marilyn and Barry Rubenstein Family
         Foundation, a tax-exempt organization under Section 501(a) of the
         Internal Revenue Code of which Mrs. Rubenstein is a trustee. Except for
         the 20,000 shares individually owned by Mrs. Rubenstein, Mrs.
         Rubenstein disclaims beneficial ownership of these securities, except
         to the extent of her pecuniary interest therein. Mrs. Rubenstein has
         sole voting power with respect to 20,000 of these shares and shared
         voting power with respect to 252,300 of these shares.

         The shares of the Company's Common Stock owned as of the date of the
IPO by all of the officers and directors of the Company have been placed in
escrow with Continental Stock Transfer & Trust Company, as escrow agent, for a
period ending March 8, 1999. During such escrow period, such persons may vote
their escrowed shares of Common Stock, but will not be able to sell or otherwise
transfer their respective shares of Common Stock, except, for estate planning
purposes, to their spouses and children (or to trusts established for their
benefit).

                         REPORT OF INDEPENDENT AUDITORS



Board of Directors and Stockholders
Healthcare Acquisition Corp.
Fort Lauderdale, Florida


         We have audited the accompanying balance sheets of Healthcare
Acquisition Corp. (a corporation in the development stage) as at December 31,
1995 and December 31, 1996 and the related statements of operations, common
stock, common stock subject to possible conversion, preferred stock, additional
paid-in capital and deficit and cash flows for the year ended December 31, 1996
and for the periods from March 21, 1995 (inception) to December 31, 1995, and
from March 21, 1995 to December 31, 1996. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

         We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

         In our opinion, the financial statements enumerated above present
fairly, in all material respects, the financial position of Healthcare
Acquisition Corp. as at December 31, 1995 and December 31, 1996 and the results
of its operations and its cash flows for the year ended December 31, 1996 and
for the periods from March 21, 1995 (inception) to December 31, 1995 and March
21, 1995 to December 31, 1996, in conformity with generally accepted accounting
principles.

         As discussed in Note 1 to the financial statements, the Company must
liquidate in the event that it does not consummate business combination, or
satisfy certain extension criteria, by September 8, 1997, and, although the
Company has signed a merger agreement with a target company, there is no
assurance that such merger will take place or that the Company will have
sufficient funds to seek another target company in the event that the proposed
merger does not take place.

                          HEALTHCARE ACQUISITION CORP.
                    (a corporation in the development stage)

                          NOTES TO FINANCIAL STATEMENTS

(NOTE 1) - ORGANIZATION AND BUSINESS OPERATIONS:

         Healthcare Acquisition Corp. (the "Company") was incorporated in
Delaware on March 21, 1995 with the objective of acquiring or merging with an
operating business in the healthcare industry. The Company's founding directors
and advisors purchased 425,000 common shares, $.001 par value, in April 1995. In
January 1996, the stockholders contributed 100,000 shares back to the Company.
In addition, in March 1996, the Company effected a 1 2/13 for 1 stock split. The
contribution and stock split have been reflected retroactively in the
accompanying financial statements. The Company has selected December 31 as its
fiscal year-end.

         The Company consummated an initial public offering of its common stock
in March and April 1996 (the "Offering") and raised net proceeds of
approximately $9,050,000. The Company's management has broad discretion with
respect to the specific application of the net proceeds of the Offering,
although substantially all of the net proceeds of the Offering are intended to
be generally applied toward consummating a business combination with an
operating business engaged in the healthcare industry (the "Business
Combination"). Furthermore, there is no assurance that the Company will be able
to successfully effect a Business Combination. As of December 31, 1996,
approximately $8,732,000 or $5.06 per share held by the Public Stockholders (as
defined below) is being held in a trust account (the "Trust Fund"), and has been
invested in government securities until the earlier of (i) the consummation of a
Business Combination or (ii) liquidation of the Company. The remaining proceeds
may be used to pay for business, legal and accounting due diligence on
prospective acquisitions, and continuing general and administrative expenses in
addition to other expenses.

         The Company, after signing a definitive agreement for the acquisition
of a target business, will submit such transaction for stockholder approval (see
Note 2). All of the Company's stockholders immediately prior to the Offering,
including all of the officers, directors and the advisors of the Company (the
"Initial Stockholders"), have agreed to vote the shares of common stock owned by
them as of the effective date of the Offering in accordance with the vote of the
majority in interest of all other stockholders of the Company (the "Public
Stockholders") with respect to any Business Combination. After consummation of
the Company's first Business Combination, this voting safeguard will no longer
be applicable.

                    (a corporation in the development stage)

                          NOTES TO FINANCIAL STATEMENTS


(NOTE 1) - ORGANIZATION AND BUSINESS OPERATIONS: (continued)

         With respect to the first Business Combination which is approved and
consummated, any Public Stockholder who votes against the Business Combination
may demand that the Company convert his shares into cash. The per share
conversion price will equal the amount in the Trust Fund as of the record date
of determination of stockholders entitled to vote on the Business Combination
divided by the number of shares held by Public Stockholders. The Company will
not consummate a Business Combination if 20% or more in interest of the Public
Stockholders exercise their conversion rights. Accordingly, Public Stockholders
holding approximately 19.99% of the aggregate number of shares owned by all
Public Stockholders may have their shares converted to cash in the event of a
Business Combination. Such Public Stockholders are entitled to receive their per
share interest in the Trust Fund, computed without regard to shares held by
Initial Stockholders.

         The Company's Certificate of Incorporation provides for mandatory
liquidation of the Company, without stockholder approval, in the event that the
Company does not consummate a Business Combination within 18 months from the
date of the consummation of the Offering March 8, 1996, or 24 months from the
consummation of the Offering if certain extension criteria have been satisfied.
In the event of liquidation, it is likely that the per share value of the
residual assets remaining available for distribution (including Trust Fund
assets) will be less than the initial public offering price per share in the
Offering.

         As discussed in Note 2, the Company has entered into a merger agreement
with Encore Orthopedics, Inc. ("Encore"). However, the completion of the merger
is contingent on among other conditions, the prior approval of the stockholders
of the Company and Encore and there is no assurance that the merger will be
consummated. In addition, the Company's current liabilities exceed its
unrestricted current assets by $86,525. Accordingly should the merger not take
place, there is no assurance that the Company will have sufficient funds to seek

                          NOTES TO FINANCIAL STATEMENTS


(NOTE 2) - MERGER AGREEMENT: (continued)

         As of December 31, 1996, the Company has incurred merger related costs
aggregating approximately $407,000 which are included as deferred merger costs
on the accompanying balance sheet. These costs, together with additional
anticipated costs relating to the merger, will be charged to expense upon either
consummation or abandonment of the merger.


(NOTE 3) - SUMMARY OF ACCOUNTING POLICIES:

         INCOME TAXES:

         The Company follows Statement of Financial Accounting Standards No. 109
("FAS 109"), "Accounting for Income Taxes". FAS 109 is an asset and liability
approach that requires the recognition of deferred tax assets and liabilities
for the expected future tax consequences of events that have been recognized in
the Company's financial statements or tax returns.

         DEFERRED FINANCING COSTS:

         Costs incurred in connection with the Company's initial bridge
financing were amortized over the term of the notes.

         NET INCOME (LOSS) PER SHARE:

         Net income (loss) per common share is computed on the basis of the
weighted average number of common shares outstanding during the period. Warrants
to purchase shares of common stock are anti-dilutive and are excluded from the
calculation.

         CASH EQUIVALENTS:

         The Company considers all highly liquid debt instruments purchased with
a maturity of three months or less to be cash equivalents.


(NOTE 4) - PUBLIC OFFERING:

         On March 13, 1996, the Company sold 1,500,000 units ("Units") in the
Offering. On March 25, 1996 and April 10, 1996, the underwriters of the Company
exercised their over-allotment option and the Company sold an additional 160,000
units and 65,000 units, respectively.

                          NOTES TO FINANCIAL STATEMENTS


(NOTE 4) - PUBLIC OFFERING: (continued)

Each Unit consists of one share of the Company's common stock, $.001 par value,
and two Redeemable Common Stock Purchase Warrants ("Warrants"). Each Warrant
entitles the holder to purchase from the Company one share of common stock at an
exercise price of $5.00 during the period commencing on the later of one year
from the effective date of the Offering (March 8, 1996) or the consummation of a
Business Combination and ending seven years from the effective date of the
Offering. The Warrants will be redeemable at a price of $.01 per warrant upon 30
days notice at any time, only in the event that the last sale price of the
common stock is at least $8.50 per share for 20 consecutive trading days ending
on the third day prior to the date on which notice of redemption is given.


(NOTE 5) - BRIDGE NOTES PAYABLE:

         In May 1995, the Company issued an aggregate of $200,000 of promissory
notes to certain accredited investors. These notes bore interest at the rate of
10% per annum and were repaid upon the consummation of the Company's Offering
with accrued interest thereon of $16,546. In addition, the investors were issued
warrants to purchase 400,000 shares of common stock (valued at $20,000) ("Bridge
Warrants") which have been accounted for as a debt discount increasing the
effective interest rate to 19%. These warrants are identical to the Warrants
discussed in Note 3, except that they are not redeemable by the Company until 90
days after the consummation of a Business Combination.


(NOTE 6) - COMMON STOCK:

           The Company has 4,300,000 shares of common stock reserved for
issuance upon exercise of the Warrants, the Bridge Warrants and underwriters'
warrants.


(NOTE 7) - PREFERRED STOCK:

         The Company is authorized to issue 1,000,000 shares of preferred stock
with such designations, voting and other rights and preferences as may be
determined from time to time by the Board of Directors.
