                FOURTH AMENDED AND RESTATED CONVERTIBLE TERM NOTE

                               DUE APRIL 30, 2005

                                                    Englewood Cliffs, New Jersey
$___________                                              As of November 4, 2002

     For value received, EpiCept Corporation, a Delaware corporation (the
"Company"), hereby promises to pay to the order of ________________________
(hereinafter referred to as the "Payee") the principal sum of $_______________
(the "Maximum Principal Amount"), or so much thereof as shall have been advanced
by Payee to the Company, with interest from the date hereof on the unpaid
balance at the rate of 8% per annum, such interest to accrue on a daily basis
from time to time from the date hereof until the date on which this Fourth
Amended and Restated Convertible Term Note (this "Note") is paid in full. This
Note is one of a series of notes being issued on the date hereof or that
hereafter may be issued to certain investors in the aggregate maximum principal
amount of $5,000,000 (this Note, together with such other notes shall be
collectively referenced to as the "Convertible Notes"). As additional
consideration for the Payee's loan to the Company of up to the Maximum Principal
Amount, the Company issued to the Payee a certain Preferred Stock Purchase
Warrant of even date herewith (as amended and/or restated, the "Stock Purchase
Warrant," and collectively with all other Stock Purchase Warrants issued to
other holders of Convertible Notes, the "Stock Purchase Warrants"). Subject to
the conversion provisions set forth in Section 5 and Section 6, all outstanding
principal and accrued interest under this Note shall become due and payable on
April 30, 2005.

     1. Further Advances. On the date hereof, the Payee has advanced to the
Company only a portion of the Maximum Principal Amount. The Company may from
time to time request additional advances under the Convertible Notes. Such
requests shall be made in writing by the Chief Executive Officer of the Company
and shall be directed to TVM IV GmbH & Co. KG ("TVM"), Merlin General Partner II
Limited as general partner of the Merlin Biosciences Fund L.P. and as managing
partner of the Merlin Biosciences Fund GbR ("Merlin") and Private Equity US
Direct Finance ("Private Equity Holding"). Each such request for an additional
advance shall also contain a detailed explanation of the reasons the additional
advance is required and a certification by the Company's Chief Executive Officer
that no Event of Default (as defined below) has occurred. Each such request
shall be made no later than 5 business days prior to the date on which the
Company requires the requested amount. Should TVM and Merlin each agree that an
additional advance should be made, TVM and Merlin shall together send a notice
to each holder of a Convertible Note indicating that portion of the Maximum
Principal Amount of their
<PAGE>
Convertible Notes that TVM and Merlin have agreed shall be advanced to the
Company, which, for the avoidance of doubt, may be for a lesser amount than that
originally requested by the Company (it being understood that each holder will
thereby become obligated to advance an equal proportion of the maximum principal
amount of his Convertible Note). Upon such notices from time to time transmitted
by TVM and Merlin in accordance with the terms of this Note, the Payee agrees to
make additional advances to the Company, provided, that the aggregate amount of
all advances by the Payee shall not exceed the Maximum Principal Amount.
Notwithstanding the foregoing, the Payee, at any time and from time to time,
upon 5 business days notice (delivered in the manner prescribed in the
Subscription Agreement pursuant to which the Note was purchased) to the Company
and each other person or entity that holds one or more of the Convertible Notes,
may advance to the Company any amount up to that amount that, together with all
amounts previously advanced to the Company by the Payee, equals the Maximum
Principal Amount. Each such advance shall be made by wire transfer to the
Company's account within three business days after receipt by the Payee of the
notice from TVM and Merlin specified above. Notwithstanding anything in the
foregoing to the contrary, no additional advances shall be made under the
Convertible Notes unless on or before November 30, 2002, the date of maturity of
that certain loan from IKB Private Equity GmbH f/k/a IKB Venture Capital GmbH
("IKB") to EpiCept GmbH (formerly known as Pharmed Labs GmbH) dated on or about
April 13, 1998 has been extended to April 30, 2004, unless TVM, Merlin and
Private Equity Holding shall unanimously waive or extend the period for
compliance with this provision.

     2. Payments. Principal and interest shall be payable in lawful money of the
United States of America, by wire transfer to a bank account designated by the
Payee or by bank check delivered to the principal office of the Payee or at such
other place as the Payee may designate from time to time in writing to the
Company.

     3. Prepayment.

          (a) The Company shall have the right at its option at any time to
prepay this Note without premium or penalty, provided, that the Company notifies
the Payee of the date that it intends to make payment on this Note not less than
twenty (20) days prior to such date so as to provide the Payee the opportunity
to convert this Note into capital stock of the Company and, provided, further,
that the Company may not prepay this Note in anticipation of an Extraordinary
Event (as defined below). Any prepayment of this Note shall be accompanied by
the interest accrued on the prepaid principal amount.

          (b) Notwithstanding anything in this Note to the contrary, if not
sooner prepaid or converted in accordance with the terms hereof, upon the
consummation of a Qualified Public Offering (as such term is defined in the
Current Charter (defined in Section 6 below)), the entire principal amount of
this Note and all accrued and unpaid interest thereon shall be prepaid by the
Company, without notice to or the consent of the Payee, with proceeds from such
offering.

     4. Principal Amount; Grid Notation. The unpaid principal balance of this
Note at any time shall be the total amount advanced by the Payee to the Company,
less the total amount of principal payments made hereon by the Company. The date
and amount of each such advance and each payment on account of the principal of
this Note may be endorsed by the Payee on the


                                        2
<PAGE>
grid attached to and made part of this Note, and when so stated shall represent
evidence thereof in the absence of manifest error. Any failure by the Payee to
so endorse shall in no way mitigate or discharge the obligation of the Company
to repay any advances actually made.

     5. Next Round Conversion. If the Company consummates a convertible
preferred stock financing with gross proceeds to the Company of at least
$10,000,000 (including the principal and accrued interest under the Convertible
Notes) and pursuant to which investors in such financing receive securities
representing a percentage of the Company's capital stock on a fully-diluted
basis immediately after the consummation of such financing equal to no more than
the Maximum Percentage of the Company (as defined below) (assuming for the
purpose of such calculation the exercise and/or conversion of all options,
warrants, preferred stock and other convertible securities) (a "Qualifying
Financing"), then, simultaneously with the closing of such Qualifying Financing,
the outstanding principal and accrued interest on this Note shall be converted
into shares of the new series of convertible preferred stock of the Company (the
"Next Round Preferred Stock") which is authorized by the Company in connection
with the Qualifying Financing. The terms of the Next Round Preferred Stock shall
be subject to negotiation by the Company and the purchasers of Next Round
Preferred Stock in the Qualifying Financing, including the Payee, and shall be
subject to the unanimous approval of each of TVM, Merlin and Private Equity
Holding. Such conversion shall occur at the lower of (i) the lowest price per
share paid by any purchaser in the Qualifying Financing and (ii) the price per
share calculated so as to assure that, immediately following such conversion of
each such Convertible Note, the shares of the Company's common stock, $0.0001
par value per share (the "Common Stock"), issuable upon conversion of the Next
Round Preferred Stock bears a proportion to the total number of shares of the
Common Stock outstanding or issuable upon exercise and/or conversion of all
options, warrants, preferred stock (including the Next Round Preferred Stock)
and other convertible securities then outstanding equal to the outstanding
principal and accrued interest on all of the Convertible Notes divided by the
sum of the outstanding principal and accrued interest on all of the Convertible
Notes and $20,000,000.00. To effect such conversion, the Payee shall on or
before the closing of the Qualifying Financing become a party to all agreements
between the Company and the purchasers of the Next Round Preferred Stock which
set forth the terms and conditions of such purchase and the Payee shall be
entitled to all the rights granted to the purchasers thereunder and subject to
any restrictions or obligations imposed generally on such purchasers. As used in
this Note, the term "Maximum Percentage of the Company" shall mean the quotient
(expressed as a percentage) obtained by dividing the aggregate consideration
paid for Next Round Preferred Stock (including the aggregate outstanding
principal and accrued interest of the Convertible Notes (the "Next Round
Consideration"), by the sum of (a) the Next Round Consideration and (b)
$15,000,000.00.

     6. Optional Conversion. So long as the Company does not consummate a
Qualifying Financing prior thereto, at any time hereinafter upon the unanimous
written election (the "Optional Conversion Election") of TVM, Merlin and Private
Equity Holding to effect the conversion of all of the Convertible Notes, the
outstanding principal and accrued interest on this Note shall be converted into
shares of a new series of the convertible preferred stock of the Company (the
"Optional Conversion Preferred Stock"), at a price per share calculated so as to
assure that, immediately following such conversion of the Convertible Notes, the
shares of the Common Stock issuable upon conversion of the Optional Conversion
Preferred Stock bears a


                                        3
<PAGE>
proportion to the total number of shares of the Company's Common Stock
outstanding or issuable upon exercise and/or conversion of all options, warrants
(excluding all Stock Purchase Warrants), preferred stock (including the Optional
Conversion Preferred Stock) and other convertible securities then outstanding
equal to the outstanding principal and accrued interest on all of the
Convertible Notes divided by the sum of the outstanding principal and accrued
interest on all of the Convertible Notes and $20,000,000.00. Such conversion
shall occur as soon as reasonably practicable after the delivery of the Optional
Conversion Election. The terms of the Optional Conversion Preferred Stock shall
be subject to negotiation by the Company and the holders of the Convertible
Notes, including the Payee, but in any event shall (a) provide that (1)upon any
liquidation or deemed liquidation event (as described in Section 1 of Article
FOURTH of the Company's Certificate of Incorporation as amended and/or restated
from time to time (the "Current Charter")) holders of Optional Convertible
Preferred Stock shall be entitled to receive on account of each of their shares
of Optional Convertible Preferred Stock first out of the assets of the Company
available to holders of the Company's capital stock, an amount not less than
three (3) times the amount per share at which the Convertible Notes are
converted into Optional Conversion Preferred Stock and (2) provide the Optional
Convertible Preferred Stock with so-called "full ratchet anti-dilution
protection," and (b) be subject to the unanimous approval of each of TVM, Merlin
and Private Equity Holding. To effect such conversion, the Company and the Payee
shall become parties to all ordinary and customary agreements necessary to fully
set forth the terms and conditions of such purchase and to provide the Payee
with all the rights, and subject the Payee to all of the restrictions or
obligations, granted to or imposed on the holders of the Optional Conversion
Preferred Stock in connection with their purchase thereof, as such rights,
restrictions and obligations may have been amended from time to time. Promptly
after the delivery by TVM, Merlin and Private Equity Holding of the Optional
Conversion Election, the Company shall use its best efforts to cause to be taken
all corporate action necessary to amend its Certificate of Incorporation to
authorize the shares of Optional Conversion Preferred Stock issuable upon
conversion of the Convertible Notes and the exercise of all Stock Purchase
Warrants and the shares of Common Stock issuable upon conversion of such shares
of Optional Conversion Preferred Stock and to effect all other changes to the
Company's Certificate of Incorporation as may be required.

     7. Mandatory Conversion. Effective immediately prior to the Effective Time
(as defined in the Merger Agreement) of the Merger, the outstanding principal
and accrued interest on this Note (which for the avoidance of doubt shall mean
any amounts in excess of that used to pay the exercise price of the Payee's
accompanying Stock Purchase Warrants) shall automatically convert, without
further act on the part of the Purchaser, into shares of Common Stock at a
conversion price of $1.50. For purposes of this Section 7, "Merger" means the
merger of Maxim Acquisition Corp., a wholly owned subsidiary of the Company with
and into Maxim Pharmaceuticals, Inc. pursuant to that certain agreement and plan
of merger (the "Merger Agreement") among the Company, Maxim Acquisition Corp.
and Maxim Pharmaceuticals Inc. dated as of September __, 2005.

     8. Payment Upon Liquidation. At the unanimous election of TVM, Merlin and
Private Equity Holding, upon the occurrence of an Extraordinary Event, the
holder hereof shall be entitled to receive (subject to Section 2.3 of the
Intercreditor Agreement (as defined below)) an amount in full satisfaction of
this Note, such amount to be paid out of the assets of the


                                        4
<PAGE>
Company before any payments are made on account of any capital stock of the
Company, equal to three (3) times the principal amount of this Note, plus all
interest accrued on this Note. The Company shall not incur any obligation
(except with respect to its issuance of Convertible Notes) outside of its
ordinary course of business after the date hereof that would be have priority
over the obligation described herein, except with the unanimous consent of TVM,
Merlin and Private Equity Holding. The Company shall not participate in an
Extraordinary Event without notifying the Payee of its intention to so
participate in such Extraordinary Event at least 10 business days prior to such
Extraordinary Event. As used in this Note, the term "Extraordinary Event" means
(a) a merger, consolidation, share exchange or other form of corporate
reorganization involving the Company in which the stockholders of the Company
immediately before such merger, consolidation, share exchange or other corporate
reorganization dispose of in excess of fifty percent (50%) of the issued and
outstanding capital stock of the Company; (b) any transaction or series of
related transactions in which (i) all or substantially all of the assets of the
Company are sold, or (ii) in excess of fifty percent (50%) of the shares of
Common Stock (assuming conversion of all convertible securities) is issued
transferred to any person (other than in a Qualifying Financing); or (c) any
event that would trigger payments to the holders of any series of the Preferred
Stock under Section 1(c) of Article FOURTH of the Current Charter in the absence
of the prescribed vote of the holders of such series to the contrary.
Notwithstanding anything in this Note to the contrary, an Extraordinary Event
shall be deemed a "Termination Event" as such term is defined in the
Intercreditor Agreement, dated as of November 4, 2002 (the "Intercreditor
Agreement"), among the Company, IKB, EpiCept GmbH, Payee, and the other holders
of Convertible Notes; if an Extraordinary Event occurs, then the proceeds of the
Extraordinary Event shall be distributed first in accordance with Section 2.3 of
the Intercreditor Agreement.

     9. Cancellation of Note. Upon conversion of this Note, in accordance with
Sections 5 or 6 hereunder, all rights with respect to this Note shall terminate,
whether or not the Note has been surrendered for cancellation, and the Company
will be forever released from its obligation under this Note, except its
obligation under Sections 5 or 6 herein.

to by the Company or any of its subsidiaries for the payment of money that,
after deducting the amount of any insurance proceeds paid or payable to or on
behalf of the Company or such subsidiary in connection with such judgment or
settlement, as the case may be, is in excess of $50,000, and such judgment shall
remain undischarged for a period of thirty (30) days, during which period
execution shall not effectively be stayed, or such settlement shall remain
unpaid for a period of thirty (30) days after the agreed payment date unless
such delay has been agreed to by the other party. If a dispute exists with
respect to the liability of any insurance underwriter under any insurance policy
of the Company or such subsidiary, no deduction under this subsection shall be
made for any portion of the insurance proceeds that are the subject of such
dispute;

this Note may be amended or waived except with the unanimous written consent of
TVM, Merlin, Private Equity Holding and the Company, and any amendment or waiver
of this Note and the other Convertible Notes made with such consent shall be
binding on all holders of the Convertible Notes (including this Note); provided,
however, that (i) no amendment or waiver respecting the amount of payment of
principal or interest on this Note shall be made without the written consent of
the holder of this Note, and (ii) the holder of this Note may waive any right or
benefit hereunder, but only as to itself, by its written consent. By

and agrees to all amendments to the Third Amended Note (defined below), the
Second Amended Note (defined below), the First Amended Note (defined below) and
the Original Note (defined below) contained in this Note. This Note supercedes

          (i) Pari Passu. The Convertible Notes rank equally and ratably without
priority over one another. No payment, including prepayment, shall be made
hereunder unless payment, including any prepayment, is made with respect to the
other Convertible Notes in an amount which bears the same ratio to the then
outstanding unpaid principal amount of such other Convertible Notes as the
payment made hereon bears to the then outstanding unpaid principal amount of
this Note.
