ITEM 5. OTHER EVENTS

DEBENTURE OFFERING

         On December 20, 2002, Halsey Drug Co., Inc. (the "Company") consummated
a private offering of securities for an approximate aggregate purchase price of
$26,385,000 (the "Offering"). The securities issued in the Offering consisted of
5% convertible senior secured debentures (the "Debentures"). The Debentures were
issued by the Company pursuant to a certain Debenture Purchase Agreement dated
December 20, 2002 (the "Purchase Agreement") by and among the Company, Care
Capital LLC ("Care Capital"), Essex Woodlands Health Ventures V ("Essex"), Galen
Partners III, L.P. and each of the Purchasers listed on the signature page
thereto (collectively, the "2002 Debenture Investor Group").

         Of the $26,385,000 million in Debentures issued in the Offering,
approximately $15,885,000 of Debentures were issued in exchange for the
surrender of like amount of principal and accrued interest outstanding under the
Company's 10% convertible promissory notes issued pursuant to various working
capital bridge loan transactions with Galen Partners III, L.P., Galen Partners
International III, L.P., Galen Employee Fund III, L.P. (collectively, "Galen")
and certain other lenders, during the period from August 15, 2001 through and
including December 20, 2002.

         The Debentures, issued at par, will become due and payable as to
principal on March 31, 2006. Interest on the principal amount of the Debentures,
at the rate of 5% per annum, is payable on a quarterly basis. With the exception
of the Debentures issued to Care Capital, interest will be paid by the Company's
issuance of a debenture instrument substantially identical to the Debentures
issued in the Offering, in the principal amount equal to the accrued interest
for each quarterly period (the "Interest Debentures"). Debentures issued to Care
Capital provide that fifty percent (50%) of the interest payments under such
Debentures will be satisfied in cash with the balance satisfied by the Company's
issuance of Interest Debentures.

         The Debentures issued to each of Care Capital and Essex are convertible
at any time after issuance into shares of the Company's Common Stock, $.01 per
value per share (the "Common Stock"). The Debentures issued to Galen and the
other investors in the Offering (excluding Care Capital and Essex) are
convertible at any time after the approval of the Company's shareholders and
debentureholders of an amendment to the Company's Certificate of Incorporation
to increase its authorized shares of Common Stock from 80,000,000 shares to such
number of shares as shall provide sufficient authorized shares to permit the
conversion of such Debentures and Company's outstanding convertible securities,
as provided in the Purchase Agreement (see "Voting Agreement" below). Subject to
the foregoing, the Debentures are convertible into shares of Common Stock at a
price per share (the "Conversion Price") of $ .34. Until such time as the
Company competes a Subsequent Material Offering (as defined below) the
Conversion Price is subject to adjustment, from time to time, to equal the
consideration per share received by the Company for its Common Stock, or the
conversion/exercise price per share of the Company's Common Stock issuable under
rights or options for the purchase of, or stock or other securities convertible
into, Common Stock


                                       2




("Convertible Securities"), if lower than the then applicable Conversion Price.
Following the Company's completion of a Subsequent Material Offering, the
Conversion Price is subject to adjustment from time to time on a
weighted-average dilution basis. A "Subsequent Material Offering" is the grant
or issuance of Common Stock or Convertible Securities by the Company during any
six month period for an aggregate gross consideration of at least $10,000,000.
The Conversion Price is also subject to adjustment to give effect to additional
Debentures, if any, that may be issued under the Purchase Agreement and in the
event of a subsequent recapitalization of the Company's outstanding common stock
purchase warrants issued to Galen in consideration for various bridge loans to
the Company.

         The Interest Debentures are convertible at any time after issuance into
shares of Common Stock at a price per share equal to the average of the closing
bid and asked prices of the Common Stock for the twenty (20) trading days
immediately preceding the applicable interest payment date under the Debentures,
as reported by the Over-the-Counter ("OTC") Bulletin Board.

         Assuming the conversion of the Debentures at the initial Conversion
Price of $ .34 per share, the Debentures are convertible into an aggregate of
approximately 77,602,000 shares of the Company's Common Stock.

         The Purchase Agreement provides that the holders of the Debentures
shall have the right to vote as part of a single class with all holders of the
Company's Common Stock on all matters to be voted on by such stockholders. Each
Debenture holder shall have such number of votes as shall equal the number of
votes he would have had if such holder converted the entire outstanding
principal amount of his Debenture into shares of Common Stock immediately prior
to the record date relating to such vote; provided, however, that any Debentures
held by Care Capital shall, for so long as they are held by Care Capital, have
no voting rights. The Purchase Agreement also provided for the execution of a
Debentureholder Agreement providing the holders of the Debentures with veto
rights relating to certain material Company transactions as further described
under the caption "Debentureholders Agreement" below.

         The Purchase Agreement provides that each of Care Capital and Essex has
the right to designate for nomination a person to be a member of the Company's
Board of Directors as of the closing date of the Offering (collectively, the
Designees"). The Purchase Agreement further provides that the Designees shall
be, if so requested by such Designee in its sole discretion, appointed to the
Company's Executive Committee, Compensation Committee and any other Committee of
the Board of Directors. Accordingly, effective as of the closing of the Purchase
Agreement, the Board of Directors appointed each of Jerry Karabelas and Immanuel
Thangaraj to the Company's Board of Directors. The Company has agreed to
nominate and appoint to the Board of Directors, subject to shareholder approval,
one designee of each of Care Capital and Essex for so long as each holds the
Debentures.



                                       3




         The Company is a party to a certain Loan Agreement with Watson
Pharmaceuticals, Inc. ("Watson") pursuant to which Watson has made a term loan
to the Company in the principal amount of $17,500,000 (the "Watson Loan
Agreement"). It was a condition to the completion of the Offering that the
Watson Loan Agreement and related agreements with Watson be amended. See "Watson
Loan Agreement Amendments" below for a description of the amendments to the
Watson Loan Agreement.

         As part of the closing of the Purchase Agreement, the Company and
certain holders of common stock purchase warrants issued in prior Company
debenture offerings in 1998 and 1999 and pursuant to bridge loan transactions
during the period 1998 through 2002, executed a certain Warrant Recapitalization
Agreement providing for the recapitalization of approximately 8,145,736 warrants
in exchange for the issuance of an aggregate of 5,970,083 shares of the
Company's Common Stock (see "Warrant Recapitalization" below).

Additional Terms of the Purchase Agreement, Debentures and Warrants

         Debentureholders Agreement

         As part of the closing of the Purchase Agreement, the Company and the
purchasers of the Debentures executed a certain Debentureholders Agreement
providing, among other things, that the approval of the holders of at least
sixty six and two-thirds percent (66 2/3%) of the aggregate principal amount of
the Debentures is required to authorize (a) any modification of the rights of
the holders of the Debentures, (b) any issuance of securities of the Company
which rank senior or pari passu to the Debentures, (c) any dividends or
distributions on, or redemption of, any securities ranking junior in priority to
the Debentures, other than dividends or distributions payable in the Company's
Common Stock or cash interest paid to individual investors in the Company's 5%
convertible senior secured debentures issued pursuant to that certain Debenture
and Warrant Purchase Agreement (the "1998 Purchase Agreement") between the
Company, Galen Partners III, L.P. and the other signatories thereto, dated March
10, 1998 (the "Galen Group Debentures") and issued pursuant to the Debenture and
Warrant Purchase Agreement (the "1999 Purchase Agreement") between the Company,
Oracle Strategic Partners, L.P. and the other signatories thereto, dated May 26,
1999 (the "Oracle Group Debentures" and together with the Galen Group
Debentures, the "Existing Debentures"), (d) the merger or consolidation of the
Company, the sale, transfer, lease or other disposition of all or substantially
all of the Company's consolidated assets, or the liquidation, recapitalization
or reorganization of the Company, other than any such transaction where the
cash, securities and/or other liquid consideration received for the voting stock
of the Company in such transaction is at least four (4) times the then
applicable conversion price of the Debentures, (e) any increase in the number of
members comprising the Company's Board of Directors above eleven (11) members,
and (f) the consummation of a strategic alliance, business combination,
licensing arrangement or other corporate partnering involving the issuance by
the Company of in excess of $10,000,000 in equity securities of the Company.


                                       4




         The Debentureholders Agreement further provides that the holders of at
least sixty six and two-thirds percent (66 2/3%) of the aggregate principal
amount of the Debentures and Existing Debentures is required in order to
authorize (a) any amendment to the Company's Certificate of Incorporation, (b)
dividends or distributions on, or redemptions of, any securities ranking junior
to the Existing Debentures, other than distributions or dividends payable in the
Company's capital stock or cash interest paid to individual investors in the
Existing Debentures, (c) any issuance of the Company's securities ranking senior
or pari passu to the Existing Debentures, and (d) the completion of any
transaction described in subsections (d), (e) and (f) in the preceding
paragraph.

         Voting Agreement

         The Company is obligated under the Purchase Agreement to solicit
shareholder approval to amend its Certificate of Incorporation to (i) provide
the holders of the Debentures with "as converted" voting rights; and (ii) to
increase its authorized shares of Common Stock from 80,000,000 to such number of
shares as shall provide sufficient authorized shares to permit the conversion of
the Debentures and the exercise and conversion of the Company's outstanding
convertible securities, including the Watson Warrant (as defined under the
caption "Watson Loan Agreement Amendments" below)(the "Charter Amendments"). The
Company anticipates soliciting shareholder approval for the Charter Amendments
at its upcoming 2003 Annual Meeting of Shareholders. In this regard, as part of
the closing of the Purchase Agreement, each of Galen Partners III, L.P., Galen
Partners International III, L.P., Galen Employee Fund III, L.P., Oracle
Strategic Partners, L.P., Michael Reicher, the Company's Chief Executive Officer
and Peter Clemens, the Company's Chief Financial Officer (collectively, the
"Voting Agreement Parties") executed a Voting Agreement dated December 20, 2002
pursuant to which each agreed to vote all of their respective voting securities
of the Company in favor of the Charter Amendments. The voting securities held by
the Voting Agreement Parties represents an aggregate of approximately 64% of the
voting rights under the Company's outstanding voting securities.

         Right of First Refusal

         The Purchase Agreement provides the holders of the Debentures and the
holders of shares of Common Stock issued upon conversion of the Debentures
(provided the Debentures remain outstanding and the shares received upon
conversion have not been sold, transferred or otherwise disposed of) as well as
the holders of the Galen Group Debentures with a right of first refusal relating
to any subsequent issuance, sale or exchange of any shares of the Company's
Common Stock or convertible securities, exclusive of certain excluded securities
and offerings in an amount less than $200,000.




                                       5



         Secured Debt


         The Debentures are secured by a lien on all assets of the Company,
tangible and intangible. In addition, each of Houba, Inc. and Halsey
Pharmaceuticals, Inc., each a wholly-owned subsidiary of the Company, has
executed in favor of the 2002 Debenture Investor Group an Unconditional
Agreement of Guaranty of the Company's obligations under the Purchase Agreement.
Each Guaranty is secured by all assets of such subsidiary, and, in the case of
Houba, Inc., by a mortgage lien on its real estate. In addition, the Company has
pledged the stock of each such subsidiary to the 2002 Debenture Investor Group
to further secure its obligations under the Purchase Agreement.

         In accordance with the terms of a Subordination Agreement dated
December 20, 2002 between the Company, the holders of the Debentures, the
holders of the Existing Debentures and Watson, the liens on the Company's and
its Subsidiaries' assets as well as the payment priority of the Debentures are
(i) subordinate to the Company's lien and payment obligations in favor of Watson
under the Watson Loan Agreement, and (ii) senior to the Company's lien and
payment obligations in favor of the holders of the Existing Debentures in the
aggregate principal amount of approximately $50,723,938. In addition to the
subordination of the liens and the payment priority of the Existing Debentures
in favor of the Debentures issued in the Offering, as part of the completion of
the Offering, each of the holders of the Galen Group Debentures and the Oracle
Group Debentures agreed to extend the maturity date of the Existing Debentures
from March 15, 2003 to March 31, 2006.

         Conversion of Debentures at Company's Option

         Provided that no event of default relating to a failure to pay
principal and interest under the Debentures shall exist and then be continuing,
in the event that following December 20, 2005, (i) the average of the closing
bid and asked prices per share of the Company's Common Stock, as reported by the
OTC Bulletin Board (or the closing price per share as reported by the NASDAQ
National Market or any Exchange on which the shares may then be traded) exceeds
the product of (x) the then applicable Conversion Price of the Debentures,
multiplied by (y) four (4), for each of the twenty (20) consecutive trading days
during which the average daily trading volume for such twenty (20) trading day
period is at least one million dollars ($1,000,000), or (ii) the Company shall
have obtained the written consent of the holders of 75% of the principal amount
of the Debentures then outstanding to convert the Debentures into Common Stock,
then the Company may upon written notice to the holders of the Debentures
require that all, but not less than all, of the outstanding principal amount of
the Debentures be converted into shares of the Company's Common Stock at a price
per share equal to the Conversion Price of the Debentures (as such Conversion
Price may be adjusted pursuant to the terms of the Purchase Agreement).


                                       6





         Registration Rights

         As part of the closing of the Purchase Agreement, the Company executed
in favor of the holders of the Debentures, the holders of the Existing
Debentures, the holders of shares received in the Warrant Recapitalization
Agreement (as described below under the caption "Warrant Recapitalization") and
Watson, a Registration Rights Agreement providing for (i) the termination of the
registration rights granted to the holders of the Existing Debentures under the
1998 Purchase Agreement and the 1999 Purchase Agreement, (ii) the termination of
the registration rights granted to Galen relating to the common stock purchase
warrants issued to Galen in consideration for various bridge loans to the
Company (the "Galen Warrants"), and (iii) the grant of registration rights to
Watson, the holders of the Debentures, the holders of the Existing Debentures,
the holders of shares of common stock received pursuant to the Warrant
Recapitalization Agreement (the "Warrant Recap Shares"), and Galen as holder of
the Galen Warrants, to register under the Securities Act of 1933, as amended,
the Warrant Recap Shares, the shares issuable on exercise of the Watson Warrant
and the Galen Warrants, and the shares issuable on conversion of the Debentures
and the Existing Debentures (collectively, the "Registrable Securities"). The
Registration Rights Agreement provides each of Galen and Watson with two (2)
demand registrations on Form S-1 (or any successor form) and the holders of 20%
of the Registrable Securities with one (1) demand registration on Form S-1 (or
any successor form). The Registration Rights Agreement also provides such
parties with unlimited piggyback registration rights.

         Other Terms

         The Purchase Agreement contains other customary terms and provisions,
including, without limitation, customary representations and warranties,
affirmative covenants, negative covenants and requirements for the provision of
certain financial information during the term that the Debentures remain
outstanding, all of which are customary for the type of securities issued in the
Offering.

         Reference is made to the Company's Press Release dated December 20,
2002 which describes, among other things, the completion of the Offering. The
Press Release is hereby incorporated by this reference and is included as
Exhibit 99.1 hereto.

WATSON LOAN AGREEMENT AMENDMENTS

         As part of the closing of the Offering, the Watson Loan Agreement was
amended to (i) extend the maturity date of the Watson Loan Agreement from March
31, 2003 to March 31, 2006, and (ii) increase the principal amount of the Watson
Term Loan from $17,500,000 to $21,401,331 to reflect the inclusion of
approximately $3,901,331 owed by the Company to Watson under a product supply
agreement between the parties.

         In consideration for the amendment to the Watson Loan Agreement, the
Company issued to Watson a Common Stock Purchase Warrant exercisable for
10,700,665 shares of the Company's


                                       7




Common Stock (the "Watson Warrant"). The Watson Warrant has a term expiring
December 31, 2009 and has an exercise price of $ .34 per share. Watson is also a
party to the Registration Rights Agreement described above under the caption
"Registration Rights".

WARRANT RECAPITALIZATION

         As part of the completion of the transactions contemplated in the
Purchase Agreement, the Company consummated the terms of a Warrant
Recapitalization Agreement dated December 20, 2002 (the "Recapitalization
Agreement") between the Company and certain holders of an aggregate of 8,145,736
Common Stock Purchase Warrants issued by the Company (i) pursuant to that

Agreement, the warrantholders as a party thereto surrendered to the Company for
cancellation the Recapitalization Warrants in exchange for the issuance of an
aggregate of 5,970,083 shares of Common Stock.
