On February 13, 1997, pursuant to Senior Secured Convertible Bridge Notes (the "Notes"), Aries Domestic used its general funds to lend $1,050,000 to the Issuer and the Aries Trust used its general funds to lend $1,950,000 to the Issuer (collectively, the "Loans"). The Notes are convertible upon certain events into a number of shares of Series D Convertible Preferred Stock at a conversion rate equal to five dollars ($5.00) per share subject to adjustment upon the occurrence of certain events. Section 3 of the Note and Warrant Purchase Agreement provides that if a Note is not paid in full at maturity and upon the occurrence of an Event of Default referred to in Section 7 of the Notes, in addition to other available remedies, the lesser of (i) the then-outstanding principal amount of such Note or (ii) 10% of the original principal amount of such Note is convertible into a number of shares of Common Stock equal to the amount converted divided by $.001. The shares of Series D Convertible Preferred Stock are convertible into 20,000,000 shares of Common Stock of the Issuer at a conversion rate equal to $.30 per share subject to adjustment upon the occurrence of certain events. Additionally, on February 13, 1997, Aries Domestic acquired (a) Class A Bridge Warrants for the purchase of 2,730,000 shares of Common Stock of the Issuer at an exercise price equal to $.001 per share and (b) Class B Bridge Warrants for the purchase of 4,270,000 shares of Common Stock of the Issuer at an exercise price equal to $.55 per share. The Aries Trust acquired (a) Class A Bridge Warrants for the purchase of 5,070,000 shares of Common Stock of the Issuer at an exercise price equal to $.001 per share and (b) Class B Bridge Warrants for the purchase of 7,930,000 shares of Common Stock of the Issuer at an exercise price equal to $.55 per share. In addition to the foregoing, prior to February 13, 1997 the Reporting Persons acquired a total of 915,000 shares of Common Stock (the "Purchased Common Stock") in open market transactions. See Item 5. The Reporting Persons disclaim beneficial ownership of all the Common Stock except the Purchased Common Stock. Item 4. Purpose of Transaction. The Reporting Persons acquired securities of the Issuer as an investment in the Issuer. While the Reporting Persons have had discussions with management and others concerning the operations and capital structure of the Issuer and changes to management, the Reporting Persons have not formulated any definitive plans regarding the operations and business of the Issuer. Pursuant to Section 7.20 of the Note and Warrant Purchase Agreement, the Reporting Persons have the right to appoint a majority of the members of the Board of Directors of the Issuer; provided, however, that in the event the Issuer has not obtained Future Financings (as defined in the Note and Warrant Purchase Agreement) in excess of $3,500,000 on or before the date which is six months after the Bridge Closing Date referred to therein, then the Reporting Persons shall have the contractual right to appoint only two directors or observers and, if additional directors have been appointed, they are required to resign. The Reporting Persons have to date not exercised such right. In connection with the Loan and the related transactions (collectively, the "Transactions"), the Issuer amended its Shareholder Rights Agreement (the "Plan") dated as of October 1, 1993, to provide that the Plan would not be applicable to the Reporting Persons and the Transactions. The Reporting Persons may from time to time acquire, or dispose of, Common Stock and/or other securities of the Issuer if and when they deem it appropriate. The Reporting Persons may formulate other purposes, plans or proposals relating to any of such securities of the Issuer to the extent deemed advisable in light of market conditions, investment policies and other factors. On February 5, 1997, two holders of Series A Convertible Preferred Stock filed an action (the "Action") in the Delaware Court of Chancery (the "Court") against the Issuer, the members of the Issuer's Board of Directors, as well as the Aries Trust and Aries Domestic, challenging the Transactions. In a conference with counsel for the parties on February 7, 1997, the Court denied a request by the plaintiffs to preclude certain elements of the Transactions. The defendants in the Action have filed answers to the complaint which deny the material allegations and raise various affirmative defenses. Aries Domestic and the Aries Trust believe that they have meritorious defenses to the claims asserted against them in the Action, and they intend to vigorously contest the claims. Page 7 of 99 Pages Except as indicated in this Schedule 13D, the Reporting Persons currently have no plans or proposals that relate to or would result in any of the matters described in subparagraphs (a) through (j) of Item 4 of Schedule 13D. Item 5. Interest in Securities of the Issuer. (a) As of February 13, 1997, Dr. Rosenwald and Paramount Capital, through acquisition of the shares by the Aries Trust and Aries Domestic, may be deemed to beneficially own 40,915,000 shares or 51.1% of the Issuer's securities, and Aries Domestic and the Aries Trust may be deemed to beneficially own the following number of shares of Common Stock: Aries Domestic 14,274,500 Aries Trust 26,640,500 The Reporting Persons disclaim beneficial ownership of all the Common Stock except the Purchased Common Stock. (b) Dr. Rosenwald and Paramount Capital share the power to vote or to direct the vote, to dispose or to direct the disposition of those shares owned by each of Aries Domestic and Aries Trust. (c) Other than the purchase of the Notes and the receipt of the Class A Warrants and the Class B Warrants, the Reporting Persons have not engaged in any transactions in the Common Stock of the Issuer in the past 60 days. See Item 3. (d) & (e) Not applicable. Item 6. Contracts, Arrangements, Understandings or Relationships with respect to Securities of the Issuer Paramount Capital is the investment manager of the Aries Trust and the General Partner of Aries Domestic and in such capacities has the authority to make certain investment decisions on behalf of such entities, including decisions relating to the securities of the Issuer. In connection with its investment management duties, Paramount Capital receives certain management fees and performance allocations from the Aries Trust and Aries Domestic. Dr. Rosenwald is the sole shareholder of Paramount Capital. Additionally, on January 28, 1997, the Issuer entered into a Letter of Intent with Paramount Capital, Inc. pursuant to which it is contemplated that Paramount Capital, Inc. will act as financial advisor and investment banker for the Issuer in future capital raising and other strategic transactions for the Issuer. Dr. Rosenwald is the sole shareholder of Paramount Capital, Inc. Except as indicated in this 13D and exhibits, there is no contract, arrangement, understanding or relationship between the Reporting Persons and any other person, with respect to any securities of the Issuer.

(b) In connection with any registration statement in which a holder of Registrable Securities is participating, each such holder shall furnish to the Company in writing such information as is reasonably requested by the Company for use in any such registration statement or prospectus and shall severally, but not jointly, indemnify, to the extent permitted by law, the Company, its directors and officers and each person, if any, who controls the Company within the meaning of the Securities Act, against any losses, claims, damages, liabilities and expenses resulting from any untrue statement or alleged untrue statement of a material fact or any omission or alleged omission of a material fact required to be stated in the registration statement or prospectus or any amendment thereof or supplement thereto or necessary to make the statements therein not misleading, but only to the extent such losses, claims, damages, liabilities or expenses are caused by an untrue statement or alleged untrue statement contained in or by an omission or alleged omission from information so furnished in writing by such holder in connection with the registration contemplated by this Section 8. If the offering pursuant to any such registration is made through underwriters, each such holder agrees to enter into an underwriting agreement in customary form with such underwriters and to indemnify such underwriters, their officers and directors, if any, and each person who controls such underwriters within the meaning of the Securities Act to the same extent as hereinabove provided with respect to indemnification by such holder of the Company. Notwithstanding the foregoing or any other provision of this Agreement, in no event shall a holder of Registrable Securities be liable for any such losses, claims, damages, liabilities or expenses in excess of the lesser of (a) the net proceeds received by such holder in the offering or (b) $1,000,000. (c) Promptly after receipt by an indemnified party under Section 8.5 (a) or (b) of notice of the commencement of any action or proceeding, such indemnified party will, if a claim in respect thereof is made against the indemnifying party under such Section, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under such Section. In case any such action or proceeding is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein, and, to the extent that it wishes, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel approved by such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under such Section for any legal or any other expenses subsequently incurred by such indemnified party in connection with the defense thereof (other than reasonable costs of investigation) unless incurred at the written request of the indemnifying party. Notwithstanding the above, the indemnified party will have the right to employ counsel of its own choice in any such action or proceeding if the indemnified party has reasonably concluded that there may be defenses available to it which are different from or additional to those of the indemnifying party, or counsel to the indemnified party is of the opinion that it would not be desirable for the same counsel to represent both the indemnifying party and the indemnified party because such representation might result in a conflict of interest (in either of which cases the indemnifying party will not have the right to assume the defense of any such action or proceeding on behalf of the indemnified party or parties and such legal and other expenses Page 32 of 99 Pages will be borne by the indemnifying party). An indemnifying party will not be liable to any indemnified party for any settlement of any such action or proceeding effected without the consent of such indemnifying party. (d) If the indemnification provided for in Section 8.5(a) or (b) is unavailable under applicable law to an indemnified party in respect of any losses, claims, damages or liabilities referred to therein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and of the holders of Registrable Securities on the other in connection with the statements or omissions which resulted in such losses, claims, damages, or liabilities, as well as any other relevant equitable considerations. The relative fault of the Company on the one hand and of the holders of Registrable Securities on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Company or by the holders of Registrable Securities and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages and liabilities referred to above shall be deemed to include, subject to the limitations set forth in Section 8.5(c), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person who is not guilty of such fraudulent misrepresentation. (e) Promptly after receipt by the Company or any holder of Securities of notice of the commencement of any action or proceeding, such party will, if a claim for contribution in respect thereof is to be made against another party (the "contributing party"), notify the contributing party of the commencement thereof; but the omission so to notify the contributing party will not relieve it from any liability which it may have to any other party other than for contribution hereunder. In case any such action, suit, or proceeding is brought against any party, and such party notifies a contributing party of the commencement thereof, the contributing party will be entitled to participate therein with the notifying party and any other contributing party similarly notified. 8.6. Additional Common Stock Issuable Upon Delay of Registration. (a) Except to the extent any delay is due to the failure of a holder to reasonably cooperate in providing to the Company such information as shall be reasonably requested by the Company in writing for use in the Shelf Registration Statement, if the Shelf Registration Statement is not filed with the Securities and Exchange Commission within the target dates set forth in the first sentence of Section 8.1 (the "Outside Target Date"), the Company shall declare and pay for no additional consideration to Purchasers additional Bridge Warrants or New Warrants, as the case may be, equal to 1.5% of the Bridge Warrants or the New Warrants, as the case may be, then held by Purchasers for each day after the Outside Target Date that the Registration Statement remains unfiled. (b) If the Shelf Registration Statement is not declared effective by the Securities and Exchange Commission within 210 days following the Closing Date (the "Targeted Effective Date"), the Company shall declare and pay for no additional consideration to Purchasers additional Bridge Warrants or New Warrants, as the case may be, equal to 1.5% of the Bridge Warrants or the New Warrants, as the case may be, then held by Purchasers for each day the Shelf Registration Statement is not declared effective by the Securities and Exchange Commission following the occurrence of the Targeted Effective Date. (c) All shares of Common Stock issuable pursuant to Section 8.6(a) and (b) shall be duly authorized, fully paid and nonassessable shares of Common Stock and shall be included in the Shelf Registration Statement contemplated by Section 8.1. Such shares shall be registered in Purchasers' names or the name of the nominee(s) of Purchasers in such denominations as Purchasers shall request pursuant to instructions delivered to the Company. 9.

GENTA INCORPORATED No.B-1 SENIOR SECURED CONVERTIBLE BRIDGE NOTE $1,050,000 New York, New York January 28, 1997 Genta Incorporated, a Delaware corporation, (the "Company"), for value received, hereby promises to pay to THE ARIES DOMESTIC FUND, LP (the "Holder"), or registered assigns, the principal sum of ONE MILLION FIFTY THOUSAND DOLLARS ($1,050,000), with interest from the date of issuance of this Senior Secured Convertible Bridge Note on the unpaid principal balance at a rate equal to twelve percent (12%) per annum, on the earlier of (a) June 30, 1997 and (b) five (5) business days following the completion of any equity offering or series of equity offerings with gross proceeds in excess of $2,500,000 (the "Maturity Date"). Payment shall be made at such place as designated by the Holder upon surrender of this Senior Secured Convertible Bridge Note, and shall be in such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts. Interest shall be computed on the basis of a 360-day year of twelve 30-day months. This Senior Secured Convertible Bridge Note is one of a duly authorized issue of Genta Incorporated 12% Senior Convertible Bridge Notes in an aggregate principal amount of $3,000,000 (individually a "Note" and collectively the "Notes") issued pursuant to a Note and Warrant Purchase Agreement of even date herewith between the Company and the Holder (the "Purchase Agreement"). The Senior Secured Convertible Bridge Notes shall be senior to all other indebtedness of the Company ("Other Indebtedness") and all Other Indebtedness shall be subordinated to the Senior Bridge Notes. These Notes are secured pursuant to the Security Agreement dated as of January 28, 1997 by and between the Company, Paramount Capital, Inc. and the Purchasers. SECTION 1. PREPAYMENT. This Note (including interest accrued on the principal hereof) may be prepaid by the Company, at any time without penalty or premium provided that the Company shall provide the holders of the Notes with at least 30 days prior written notice of prepayment, and prior to such prepayment, the holders of the Notes shall have the opportunity to exercise their optional conversion rights pursuant to Section 2 hereof. SECTION 2. OPTIONAL CONVERSION (a) Right of Conversion. (i) Immediately, or, (ii) if the rules of the Nasdaq National Market or any other law or regulation, require the approval of the shareholders of the Company to permit convertibility of the Notes, then upon the receipt of such approvals, the Notes shall be convertible, in whole or in part, at the option of the holder thereof and upon notice to the Corporation as set forth in paragraph 2(b) below, into the number of shares of Series D Preferred Stock of the Company (the "Preferred Stock") equal to the Conversion Amount divided by the then current Conversion Price (as defined below). The Conversion Amount shall be the Liquidation Amount, or in the case of a partial conversion, such lesser amount as designated by the converting holder. The Liquidation Amount shall be the aggregate principal value of the Notes held by such Holder plus any accrued and unpaid interest. The Conversion Price shall initially be $5.00, subject to adjustment as provided below, representing an initial conversion rate (subject to adjustment) of 2000 shares of Preferred Stock per $10,000 of Conversion Amount. Page 39 of 99 Pages (b) Conversion Procedures. Any holder of Notes desiring to convert such Notes into Preferred Stock shall surrender the Notes at the offices of the Company, which Notes shall be accompanied by irrevocable written notice to the Corporation that the holder elects so to convert such Notes and specifying the name or names (with address) in which a certificate or certificates evidencing shares of Preferred Stock are to be issued. The Corporation will make a notation of the date that a notice of conversion is received, which date shall be deemed to be the date of receipt for purposes hereof. The Corporation shall deliver to the holder converting the Notes, or to the nominee or nominees of such person, certificates evidencing the number of full shares of Preferred Stock to which such person shall be entitled as aforesaid, together with a cash adjustment of any fraction of a share as hereinafter provided. Subject to the following provisions of this paragraph, such conversion shall be deemed to have been made as of the date of such surrender of the Notes and the person or persons entitled to receive the Preferred Stock deliverable upon conversion of such Notes shall be treated for all purposes as the record holder or holders of such Preferred Stock on such date; provided, however, that the Corporation shall not be required to convert any Notes while the stock transfer books of the Corporation are closed for any purpose, but the surrender of Notes for conversion during any period while such books are so closed shall become effective for conversion immediately upon the reopening of such books as if the surrender had been made on the date of such reopening, and the conversion shall be at the conversion rate in effect on such date. All notices of conversion shall be irrevocable; provided, however, that if the Corporation has sent notice of an event pursuant to paragraph 2(e) hereof, a holder of Notes may, at its election, provide in its notice of conversion that the conversion of its Notes shall be contingent upon the occurrence of the record date or effectiveness of such event (as specified by such holder), provided that such notice of conversion is received by the Corporation prior to such record date or effective date, as the case may be. (c) Protection From Dilution. (i) If, at any time or from time to time after the date of this Note, the Company shall issue or distribute to the holders of shares of Preferred Stock evidence of its indebtedness, any other securities of the Company or any cash, property or other assets (excluding a subdivision, combination or reclassification, or dividend or distribution payable solely to holders of Preferred Stock in shares of Preferred Stock, referred to in Subsection (c)(ii), and also excluding cash dividends or cash distributions paid out of net profits legally available therefor in the full amount thereof (any such non-excluded event being herein called a "SPECIAL DIVIDEND"), the Conversion Price shall be adjusted by multiplying the Conversion Price then in effect by a fraction, the numerator of which shall be the then Current Market Price Per Share of Preferred Stock in effect on the record date of such issuance or distribution less the fair market value (as determined in good faith by the Company's Board of Directors) of the evidence of indebtedness, cash, securities or property, or other assets issued or distributed in such Special Dividend applicable to one share of Preferred Stock and the denominator of which shall be the then Current Market Price Per Share of Preferred Stock in effect on the record date of such issuance or distribution. An adjustment made pursuant to this Subsection 2(a) shall become effective immediately after the record date of any such Special Dividend. The then "CURRENT MARKET PRICE PER SHARE OF PREFERRED STOCK" shall equal the then Current Market Price multiplied by the then effective "conversion rate" (as defined and used in the Certificate of Designation for the Series D Preferred Stock). The then Current Market Price per share (the "CURRENT MARKET PRICE") shall be deemed to be the last sale price of the Common Stock on the trading day prior to such date or, in case no such reported sales take place on such day, the average of the last reported bid and asked prices of the Common Stock on such day, in either case on the principal national securities exchange on which the Common Stock is admitted to trading or listed, or if not listed or admitted to trading on any such exchange, the representative closing bid price of the Common Stock as reported by the National Association of Securities Dealers, Inc. Automated Quotations System ("NASDAQ"), or other similar organization if NASDAQ is no longer reporting such information, or, if the Common Stock is not reported on NASDAQ, the high per share bid price for the Common Stock in the over-the-counter market as reported by the National Quotation Bureau or similar organization, or if not so available, the fair market value of the Common Stock as determined in good faith by the Board of Directors. (ii) In case the Company shall hereafter (i) pay a dividend or make a distribution on its capital stock in shares of Preferred Stock, (ii) subdivide its outstanding shares of Preferred Stock into a greater number of shares, (iii) combine its outstanding shares of Preferred Stock into a smaller number of shares or (iv) issue by Page 40 of 99 Pages reclassification of its Preferred Stock any shares of capital stock of the Company (other than the Conversion Shares), the Conversion Price shall be proportionately adjusted so that the Notes shall be convertible into a number and kind of securities which the holders would have been entitled to receive after any such event had they converted the Notes immediately prior thereto. An adjustment made pursuant to this Subsection 2(c)(ii) shall become effective immediately after the record date in the case of a dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or reclassification. (iii) Except as provided in Subsections (c)(i) and (c)(iv), in case the Company shall hereafter issue or sell any Preferred Stock, any securities convertible into Preferred Stock, any rights, options or warrants to purchase Preferred Stock or any securities convertible into Preferred Stock, in each case for a price per share or entitling the holders thereof to purchase Preferred Stock at a price per share (determined by dividing (i) the total amount, if any, received or receivable by the Company in consideration of the issuance or sale of such securities plus the total consideration, if any, payable to the Company upon exercise or conversion thereof (the "TOTAL CONSIDERATION") by (ii) the number of additional shares of Preferred Stock issuable upon exercise or conversion of such securities) which is less than either the then Current Market Price Per Share of Preferred Stock in effect on the date of such issuance or sale or the Conversion Price, the Conversion Price shall be adjusted as of the date of such issuance or sale by multiplying the Conversion Price then in effect by a fraction, the numerator of which shall be (x) the sum of (A) the number of shares of Preferred Stock outstanding on the record date of such issuance or sale plus (B) the Total Consideration divided by the Current Market Price Per Share of Preferred Stock or the current Conversion Price, whichever is greater, and the denominator of which shall be (y) the number of shares of Preferred Stock outstanding on the record date of such issuance or sale plus the maximum number of additional shares of Preferred Stock issued, sold or issuable upon exercise or conversion of such securities. (iv) In case of any capital reorganization or reclassification, or any consolidation or merger to which the Company is a party other than a merger or consolidation in which the Company is the continuing corporation, or in case of any sale or conveyance to another entity of the property of the Company as an entirety or substantially as a entirety, or in the case of any statutory exchange of securities with another corporation (including any exchange effected in connection with a merger of a third corporation into the Company), the Holder of this Note shall have the right thereafter to receive on the conversion of this Note the kind and amount of securities, cash or other property which the Holder would have owned or have been entitled to receive immediately after such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance had this Note been converted immediately prior to the effective date of such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance and in any such case, if necessary, appropriate adjustment shall be made in the application of the provisions set forth in this Section 2 with respect to the rights and interests thereafter of the Holder of this Note to the end that the provisions set forth in this Section 2 shall thereafter correspondingly be made applicable, as nearly as may reasonably be, in relation to any shares of stock or other securities or property thereafter deliverable on the Note. The above provisions of this Subsection (c)(iv) shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, statutory exchanges, sales or conveyances. The Company shall require the issuer of any shares of stock or other securities or property thereafter deliverable on the exercise of this Note to be responsible for all of the agreements and obligations of the Company hereunder. Notice of any such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance and of said provisions so proposed to be made, shall be mailed to the Holders of the Notes not less than 30 days prior to such event. A sale of all or substantially all of the assets of the Company for a consideration consisting primarily of securities shall be deemed a consolidation or merger for the foregoing purposes. (v) In case any event shall occur as to which the other provisions of this Section 2 are not strictly applicable but as to which the failure to make any adjustment would not fairly protect the conversion rights represented by this Note in accordance with the essential intent and principles hereof then, in each such case, the Holders of Notes may appoint a firm of independent public accountants of recognized national standing reasonably acceptable to the Company, which shall give their opinion as to the adjustment, if any, on a basis consistent with the essential intent and principles established herein, necessary to preserve the conversion rights. Upon receipt of such opinion, the Company will promptly mail a copy thereof to the Holder of this Note and shall make the adjustments described therein. The fees and expenses of such independent public accountants shall be borne by the Company. Page 41 of 99 Pages (vi) For purposes of the anti-dilution protection contained in this Section (c), at all times following the conversion of all shares of Preferred Stock into shares of Common Stock, the term Preferred Stock shall be read to be Common Stock, context permitting, so that the anti-dilution provisions will continue to protect the conversion rights represented by this Note after the conversion of all the Preferred Stock into the Common Stock in accordance with the essential intent and principles of this Section 3 (it being understood that prior to such conversion, the anti-dilution provisions of the Preferred Stock underlying this Note shall be applicable to any dilutive events with respect to the Common Stock and protect the Holder from dilution of the Common Stock). (d) Reservation of Shares; Transfer Taxes; Etc. The Corporation shall at all times reserve and keep available, out of its authorized and unissued shares of Preferred Stock, solely for the purpose of effecting the conversion of the Notes, such number of shares of its Preferred Stock free of preemptive rights as shall be sufficient to effect the conversion of all Notes from time to time outstanding. The Corporation shall use its best efforts from time to time, in accordance with the laws of the State of Delaware, to increase the authorized number of shares of Preferred Stock if at any time the number of shares of Preferred Stock not outstanding shall not be sufficient to permit the conversion of all the then-outstanding Notes. The Corporation shall pay any and all issue or other taxes that may be payable in respect of any issue or delivery of shares of Preferred Stock on conversion of the Notes. The Corporation shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue or delivery of Preferred Stock (or other securities or assets) in a name other than that in which the Notes so converted were registered, and no such issue or delivery shall be made unless and until the person requesting such issue has paid to the Corporation the amount of such tax or has established, to the satisfaction of the Corporation, that such tax has been paid. (e) Prior Notice of Certain Events. In case: (i) the Corporation shall declare any dividend (or any other distribution); or (ii) the Corporation shall authorize the granting to the holders of Preferred Stock of rights or warrants to subscribe for or purchase any shares of stock of any class or of any other rights or warrants; or (iii) of any reclassification of Preferred Stock (other than a subdivision or combination of the outstanding Preferred Stock, or a change in par value, or from par value to no par value, or from no par value to par value); or (iv) of any consolidation or merger to which the Corporation is a party and for which approval of any stockholders of the Corporation shall be required, or of the sale or transfer of all or substantially all of the assets of the Corporation or of any compulsory share exchange whereby the Preferred Stock is converted into other securities, cash or other property; or (v) of the voluntary or involuntary dissolution, liquidation or winding up of the Corporation; then the Corporation shall cause to be mailed to the holders of Notes, at their last addresses as they shall appear upon the books of the Corporation, at least 20 days prior to the applicable record date hereinafter specified, a notice stating (x) the date on which a record (if any) is to be taken for the purpose of such dividend, distribution or granting of rights or warrants or, if a record is not to be taken, the date as of which the holders of Preferred Stock of record to be entitled to such dividend, distribution, rights or warrants are to be determined and a description of the cash, securities or other property to be received by such holders upon such dividend, distribution or granting of rights or warrants or (y) the date on which such reclassification, consolidation, merger, sale, transfer, share exchange, dissolution, liquidation or winding up or other liquidation event is expected to become effective, the date as of which it is expected that holders of Preferred Stock of record shall be entitled to exchange their shares of Preferred Stock for securities or other property deliverable upon such exchange, dissolution, liquidation or winding up or other liquidation event and the consideration, including securities or other property, to be received by such holders upon such exchange; provided, however, that no failure to mail such Page 42 of 99 Pages notice or any defect therein or in the mailing thereof shall affect the validity of the corporate action required to be specified in such notice. (f) Other Changes in Conversion Rate. The Corporation from time to time may increase the Conversion Rate by any amount for any period of time if the period is at least 20 days and if the increase is irrevocable during the period. Whenever the Conversion Rate is so increased, the Corporation shall mail to holders of record of Notes a notice of the increase at least 15 days before the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period it will be in effect. The Corporation may make such increases in the Conversion Rate, in addition to those required or allowed by this paragraph 4, as shall be determined by it, as evidenced by a resolution of the Board of Directors, to be advisable in order to avoid or diminish any income tax to holders of Common Stock resulting from any dividend or distribution of stock or issuance of rights or warrants to purchase or subscribe for stock or from any event treated as such for income tax purposes. SECTION 3. DEFAULT CONVERSION. (a) If this Note and all accrued interest shall not have been paid in full on or before the Maturity Date or upon the occurrence of an Event of Default (as defined in Section 7 hereof), the Holder shall have the right (the "Default Conversion Right"), in addition to any other available remedies set forth in Section 8 hereof or at law or in equity, to convert up to the lesser of (i) the then outstanding principal amount of this Note or (ii) 10% of the original principal amount of this Note, into the number of shares of Common Stock of the Company ("Common Stock"), equal to the amount converted by the Noteholder upon such Event of Default (the "Default Conversion Amount") divided by $.001 (the "Default Conversion Price"). Upon conversion, the Company shall pay all accrued and unpaid interest on the Default Conversion Amount. (b) To exercise the Default Conversion Right, the Holder, on or before the 60th day after the Maturity Date, but before payment in full of the then outstanding principal and interest under this Note, shall deliver to the Company, at its office at as set forth in section 11, or at such other place as is designated in writing by the Company, a notice (the "Conversion Notice") stating that the Holder is exercising the Default Conversion Right, the Default Conversion Amount and the name or names in which the Holder wishes the certificates for shares of Common Stock to be issued. (c) To the extent permitted by applicable law, upon exercise of the Default Conversion Right, the Holder shall be deemed to be the holder of record of the shares of Common Stock issuable upon such exercise (the "Conversion Shares"), notwithstanding that the transfer books of the Company shall then be closed or certificates representing such Conversion Shares shall not then have been actually delivered to the Holder. As soon as practicable and in any event within five (5) days after exercise of the Default Conversion Right, the Company shall issue and deliver to the Holder a certificate or certificates evidencing the Conversion Shares registered in the name of the Holder or its designee, provided that the Company may require the holder, by notice given to the Holder promptly after receipt of the Conversion Notice, as a condition to the delivery of such certificate or certificates, to present this Note to the Company for the placement hereon of a legend indicating that the Default Conversion Right has been exercised to the extent of the Default Conversion Amount, and this Note (unless thereby paid in full) shall be immediately returned to the Holder. (d) The issuance of any shares or other securities upon the exercise of the Default Conversion Right, and the delivery of certificates or other instruments representing such shares or other securities, shall be made without charge to the Holder for any tax or other charge in respect of such issuance. The Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of any certificate in a name other than that of the Holder and the Company shall not be required to issue or deliver any such certificate unless and until the person or persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. (e) The Holder shall not have, solely on account of such status as a Holder of this Note, any rights of a stockholder of the Company, either at law or in equity, or any notice of meetings of stockholders or of any other proceedings of the Company except as provided in this Note. Page 43 of 99 Pages (f) The Company shall at all times following the Issuance Date, reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose of providing for the exercise of the Default Conversion Right, such number of shares of Common Stock as shall, from time to time, be sufficient for the exercise of the Default Conversion Right in full. The Company covenants that all shares of Common Stock issuable upon exercise of the Default Conversion Right shall be validly issued, fully paid and nonassessable. (g) The anti-dilution protections set forth in Section 2(c) hereof shall apply as well to the Default Conversion Right and the adjustment of the Default Conversion Price hereunder, provided, however, that for purposes of such application all appropriate references to Preferred Stock shall be read as references to Common Stock and all references to the Conversion Price shall be read as references to the Default Conversion Price, so as to give the Default Conversion Rights, as nearly as practicable, the anti-dilution and other protections provided for in section 2(c) with respect to the Optional Conversion Right. SECTION 4. FRACTIONAL SHARES. (a) The Company shall not be required to issue fractions of shares of Common Stock or other capital stock of the Company upon the exercise of the Optional and Default Conversion Right. If any fraction of a share would be issuable on any exercise of the Optional or Default Conversion Right (or specified portions thereof), the Company shall purchase such fraction for an amount in cash equal to the same fraction of the closing price for the Common Stock on the trading date immediately preceding the date of exercise of the Optional or Default Conversion Right. SECTION 5. AFFIRMATIVE COVENANTS OF THE COMPANY. The Company covenants and agrees that until the payment in full of this Note, the Company shall: (a) Existence; Business.

Declare or pay, directly or indirectly, any dividend or make any other distribution (by reduction of capital or otherwise), whether in cash, property, securities or a combination thereof, with respect to any shares of its capital stock or directly or indirectly redeem, purchase, retire or otherwise acquire for value any shares of any class of its capital stock or set aside any amount for any such purpose, except as permitted by Section 7.15 of the Note and Warrant Agreement. (f) No Impairment.

This Senior Secured Convertible Bridge Note is one of a duly authorized issue of Genta Incorporated 12% Senior Convertible Bridge Notes in an aggregate principal amount of $3,000,000 (individually a "Note" and collectively the "Notes") issued pursuant to a Note and Warrant Purchase Agreement of even date herewith between the Company and the Holder (the "Purchase Agreement"). The Senior Secured Convertible Bridge Notes shall be senior to all other indebtedness of the Company ("Other Indebtedness") and all Other Indebtedness shall be subordinated to the Senior Bridge Notes. These Notes are secured pursuant to the Security Agreement dated as of January 28, 1997 by and between the Company, Paramount Capital, Inc. and the Purchasers. SECTION 1. PREPAYMENT. This Note (including interest accrued on the principal hereof) may be prepaid by the Company, at any time without penalty or premium provided that the Company shall provide the holders of the Notes with at least 30 days prior written notice of prepayment, and prior to such prepayment, the holders of the Notes shall have the opportunity to exercise their optional conversion rights pursuant to Section 2 hereof. SECTION 2. OPTIONAL CONVERSION (a) Right of Conversion. (i) Immediately, or, (ii) if the rules of the Nasdaq National Market or any other law or regulation, require the approval of the shareholders of the Company to permit convertibility of the Notes, then upon the receipt of such approvals, the Notes shall be convertible, in whole or in part, at the option of the holder thereof and upon notice to the Corporation as set forth in paragraph 2(b) below, into the number of shares of Series D Preferred Stock of the Company (the "Preferred Stock") equal to the Conversion Amount divided by the then current Conversion Price (as defined below). The Conversion Amount shall be the Liquidation Amount, or in the case of a partial conversion, such lesser amount as designated by the converting holder. The Liquidation Amount shall be the aggregate principal value of the Notes held by such Holder plus any accrued and unpaid interest. The Conversion Price shall initially be $5.00, subject to adjustment as provided below, representing an initial conversion rate (subject to adjustment) of 2000 shares of Preferred Stock per $10,000 of Conversion Amount. Page 50 of 100 Pages (b) Conversion Procedures. Any holder of Notes desiring to convert such Notes into Preferred Stock shall surrender the Notes at the offices of the Company, which Notes shall be accompanied by irrevocable written notice to the Corporation that the holder elects so to convert such Notes and specifying the name or names (with address) in which a certificate or certificates evidencing shares of Preferred Stock are to be issued. The Corporation will make a notation of the date that a notice of conversion is received, which date shall be deemed to be the date of receipt for purposes hereof. The Corporation shall deliver to the holder converting the Notes, or to the nominee or nominees of such person, certificates evidencing the number of full shares of Preferred Stock to which such person shall be entitled as aforesaid, together with a cash adjustment of any fraction of a share as hereinafter provided. Subject to the following provisions of this paragraph, such conversion shall be deemed to have been made as of the date of such surrender of the Notes and the person or persons entitled to receive the Preferred Stock deliverable upon conversion of such Notes shall be treated for all purposes as the record holder or holders of such Preferred Stock on such date; provided, however, that the Corporation shall not be required to convert any Notes while the stock transfer books of the Corporation are closed for any purpose, but the surrender of Notes for conversion during any period while such books are so closed shall become effective for conversion immediately upon the reopening of such books as if the surrender had been made on the date of such reopening, and the conversion shall be at the conversion rate in effect on such date. All notices of conversion shall be irrevocable; provided, however, that if the Corporation has sent notice of an event pursuant to paragraph 2(e) hereof, a holder of Notes may, at its election, provide in its notice of conversion that the conversion of its Notes shall be contingent upon the occurrence of the record date or effectiveness of such event (as specified by such holder), provided that such notice of conversion is received by the Corporation prior to such record date or effective date, as the case may be. (c) Protection From Dilution. (i) If, at any time or from time to time after the date of this Note, the Company shall issue or distribute to the holders of shares of Preferred Stock evidence of its indebtedness, any other securities of the Company or any cash, property or other assets (excluding a subdivision, combination or reclassification, or dividend or distribution payable solely to holder of Preferred Stock in shares of Preferred Stock, referred to in Subsection (c)(ii), and also excluding cash dividends or cash distributions paid out of net profits legally available therefor in the full amount thereof (any such non-excluded event being herein called a "SPECIAL DIVIDEND"), the Conversion Price shall be adjusted by multiplying the Conversion Price then in effect by a fraction, the numerator of which shall be the then Current Market Price Per Share of Preferred Stock in effect on the record date of such issuance or distribution less the fair market value (as determined in good faith by the Company's Board of Directors) of the evidence of indebtedness, cash, securities or property, or other assets issued or distributed in such Special Dividend applicable to one share of Preferred Stock and the denominator of which shall be the then Current Market Price Per Share of Preferred Stock in effect on the record date of such issuance or distribution. An adjustment made pursuant to this Subsection 2(a) shall become effective immediately after the record date of any such Special Dividend. The then "CURRENT MARKET PRICE PER SHARE OF PREFERRED STOCK" shall equal the then Current Market Price multiplied by the then effective "conversion rate" (as defined and used in the Certificate of Designation for the Series D Preferred Stock). The then Current Market Price per share (the "CURRENT MARKET PRICE") shall be deemed to be the last sale price of the Common Stock on the trading day prior to such date or, in case no such reported sales take place on such day, the average of the last reported bid and asked prices of the Common Stock on such day, in either case on the principal national securities exchange on which the Common Stock is admitted to trading or listed, or if not listed or admitted to trading on any such exchange, the representative closing bid price of the Common Stock as reported by the National Association of Securities Dealers, Inc. Automated Quotations System ("NASDAQ"), or other similar organization if NASDAQ is no longer reporting such information, or, if the Common Stock is not reported on NASDAQ, the high per share bid price for the Common Stock in the over-the-counter market as reported by the National Quotation Bureau or similar organization, or if not so available, the fair market value of the Common Stock as determined in good faith by the Board of Directors. Page 51 of 99 Pages (ii) In case the Company shall hereafter (i) pay a dividend or make a distribution on its capital stock in shares of Preferred Stock, (ii) subdivide its outstanding shares of Preferred Stock into a greater number of shares, (iii) combine its outstanding shares of Preferred Stock into a smaller number of shares or (iv) issue by reclassification of its Preferred Stock any shares of capital stock of the Company (other than the Conversion Shares), the Conversion Price shall be proportionately adjusted so that the Notes shall be convertible into a number and kind of securities which the holders would have been entitled to receive after any such event had they converted the Notes immediately prior thereto. An adjustment made pursuant to this Subsection 2(b) shall become effective immediately after the record date in the case of a dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or reclassification. (iii) Except as provided in Subsections (c)(i) and (c)(iv), in case the Company shall hereafter issue or sell any Preferred Stock, any securities convertible into Preferred Stock, any rights, options or warrants to purchase Preferred Stock or any securities convertible into Preferred Stock, in each case for a price per share or entitling the holders thereof to purchase Preferred Stock at a price per share (determined by dividing (i) the total amount, if any, received or receivable by the Company in consideration of the issuance or sale of such securities plus the total consideration, if any, payable to the Company upon exercise or conversion thereof (the "TOTAL CONSIDERATION") by (ii) the number of additional shares of Preferred Stock issuable upon exercise or conversion of such securities) which is less than either the then Current Market Price Per Share of Preferred Stock in effect on the date of such issuance or sale or the Conversion Price, the Conversion Price shall be adjusted as of the date of such issuance or sale by multiplying the Conversion Price then in effect by a fraction, the numerator of which shall be (x) the sum of (A) the number of shares of Preferred Stock outstanding on the record date of such issuance or sale plus (B) the Total Consideration divided by the Current Market Price Per Share of Preferred Stock or the current Conversion Price, whichever is greater, and the denominator of which shall be (y) the number of shares of Preferred Stock outstanding on the record date of such issuance or sale plus the maximum number of additional shares of Preferred Stock issued, sold or issuable upon exercise or conversion of such securities. (iv) In case of any capital reorganization or reclassification, or any consolidation or merger to which the Company is a party other than a merger or consolidation in which the Company is the continuing corporation, or in case of any sale or conveyance to another entity of the property of the Company as an entirety or substantially as a entirety, or in the case of any statutory exchange of securities with another corporation (including any exchange effected in connection with a merger of a third corporation into the Company), the Holder of this Note shall have the right thereafter to receive on the conversion of this Note the kind and amount of securities, cash or other property which the Holder would have owned or have been entitled to receive immediately after such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance had this Note been converted immediately prior to the effective date of such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance and in any such case, if necessary, appropriate adjustment shall be made in the application of the provisions set forth in this Section 2 with respect to the rights and interests thereafter of the Holder of this Note to the end that the provisions set forth in this Section 2 shall thereafter correspondingly be made applicable, as nearly as may reasonably be, in relation to any shares of stock or other securities or property thereafter deliverable on the Note. The above provisions of this Subsection (c)(iv) shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, statutory exchanges, sales or conveyances. The Company shall require the issuer of any shares of stock or other securities or property thereafter deliverable on the exercise of this Note to be responsible for all of the agreements and obligations of the Company hereunder. Notice of any such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance and of said provisions so proposed to be made, shall be mailed to the Holders of the Notes not less than 30 days prior to such event. A sale of all or substantially all of the assets of the Company for a consideration consisting primarily of securities shall be deemed a consolidation or merger for the foregoing purposes. (v) In case any event shall occur as to which the other provisions of this Section 2 are not strictly applicable but as to which the failure to make any adjustment would not fairly protect the conversion rights represented by this Note in accordance with Page 52 of 99 Pages the essential intent and principles hereof then, in each such case, the Holders of Notes may appoint a firm of independent public accountants of recognized national standing reasonably acceptable to the Company, which shall give their opinion as to the adjustment, if any, on a basis consistent with the essential intent and principles established herein, necessary to preserve the conversion rights. Upon receipt of such opinion, the Company will promptly mail a copy thereof to the Holder of this Note and shall make the adjustments described therein. The fees and expenses of such independent public accountants shall be borne by the Company. (vi) For purposes of the anti-dilution protection contained in this Section (c), at all times following the conversion of all shares of Preferred Stock into shares of Common Stock, the term Preferred Stock shall be read to be Common Stock, context permitting, so that the anti-dilution provisions will continue to protect the conversion rights represented by this Note after the conversion of all the Preferred Stock into the Common Stock in accordance with the essential intent and principles of this Section 3 (it being understood that prior to such conversion, the anti-dilution provisions of the Preferred Stock underlying this Note shall be applicable to any dilutive events with respect to the Common Stock and protect the Holder from dilution of the Common Stock). (d) Reservation of Shares; Transfer Taxes; Etc. The Corporation shall at all times reserve and keep available, out of its authorized and unissued shares of Preferred Stock, solely for the purpose of effecting the conversion of the Notes, such number of shares of its Preferred Stock free of preemptive rights as shall be sufficient to effect the conversion of all Notes from time to time outstanding. The Corporation shall use its best efforts from time to time, in accordance with the laws of the State of Delaware, to increase the authorized number of shares of Preferred Stock if at any time the number of shares of Preferred Stock not outstanding shall not be sufficient to permit the conversion of all the then-outstanding Notes. The Corporation shall pay any and all issue or other taxes that may be payable in respect of any issue or delivery of shares of Preferred Stock on conversion of the Notes. The Corporation shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue or delivery of Preferred Stock (or other securities or assets) in a name other than that in which the Notes so converted were registered, and no such issue or delivery shall be made unless and until the person requesting such issue has paid to the Corporation the amount of such tax or has established, to the satisfaction of the Corporation, that such tax has been paid. (e) Prior Notice of Certain Events. In case: (i) the Corporation shall declare any dividend (or any other distribution); or (ii) the Corporation shall authorize the granting to the holders of Preferred Stock of rights or warrants to subscribe for or purchase any shares of stock of any class or of any other rights or warrants; or (iii) of any reclassification of Preferred Stock (other than a subdivision or combination of the outstanding Preferred Stock, or a change in par value, or from par value to no par value, or from no par value to par value); or (iv) of any consolidation or merger to which the Corporation is a party and for which approval of any stockholders of the Corporation shall be required, or of the sale or transfer of all or substantially all of the assets of the Corporation or of any compulsory share exchange whereby the Preferred Stock is converted into other securities, cash or other property; or (v) of the voluntary or involuntary dissolution, liquidation or winding up of the Corporation; then the Corporation shall cause to be mailed to the holders of Notes, at their last addresses as they shall appear upon the books of the Corporation, at least 20 days prior to the applicable record date hereinafter specified, a notice stating (x) the date on which a record (if any) is to be taken for the purpose of such dividend, distribution or granting of rights or warrants or, if a record is not to be taken, the date as of which the holders of Page 53 of 99 Pages Preferred Stock of record to be entitled to such dividend, distribution, rights or warrants are to be determined and a description of the cash, securities or other property to be received by such holders upon such dividend, distribution or granting of rights or warrants or (y) the date on which such reclassification, consolidation, merger, sale, transfer, share exchange, dissolution, liquidation or winding up or other liquidation event is expected to become effective, the date as of which it is expected that holders of Preferred Stock of record shall be entitled to exchange their shares of Preferred Stock for securities or other property deliverable upon such exchange, dissolution, liquidation or winding up or other liquidation event and the consideration, including securities or other property, to be received by such holders upon such exchange; provided, however, that no failure to mail such notice or any defect therein or in the mailing thereof shall affect the validity of the corporate action required to be specified in such notice. (f) Other Changes in Conversion Rate. The Corporation from time to time may increase the Conversion Rate by any amount for any period of time if the period is at least 20 days and if the increase is irrevocable during the period. Whenever the Conversion Rate is so increased, the Corporation shall mail to holders of record of Notes a notice of the increase at least 15 days before the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period it will be in effect. The Corporation may make such increases in the Conversion Rate, in addition to those required or allowed by this paragraph 4, as shall be determined by it, as evidenced by a resolution of the Board of Directors, to be advisable in order to avoid or diminish any income tax to holders of Common Stock resulting from any dividend or distribution of stock or issuance of rights or warrants to purchase or subscribe for stock or from any event treated as such for income tax purposes. SECTION 3. DEFAULT CONVERSION. (a) If this Note and all accrued interest shall not have been paid in full on or before the Maturity Date or upon the occurrence of an Event of Default (as defined in Section 7 hereof), the Holder shall have the right (the "Default Conversion Right"), in addition to any other available remedies set forth in Section 8 hereof or at law or in equity, to convert up to the lesser of (i) the then outstanding principal amount of this Note or (ii) 10% of the original principal amount of this Note, into the number of shares of Common Stock of the Company ("Common Stock"), equal to the amount converted by the Noteholder upon such Event of Default (the "Default Conversion Amount") divided by $.001 (the "Default Conversion Price"). Upon conversion, the Company shall pay all accrued and unpaid interest on the Default Conversion Amount. (b) To exercise the Default Conversion Right, the Holder, on or before the 60th day after the Maturity Date, but before payment in full of the then outstanding principal and interest under this Note, shall deliver to the Company, at its office at as set forth in section 11, or at such other place as is designated in writing by the Company, a notice (the "Conversion Notice") stating that the Holder is exercising the Default Conversion Right, the Default Conversion Amount and the name or names in which the Holder wishes the certificates for shares of Common Stock to be issued. (c) To the extent permitted by applicable law, upon exercise of the Default Conversion Right, the Holder shall be deemed to be the holder of record of the shares of Common Stock issuable upon such exercise (the "Conversion Shares"), notwithstanding that the transfer books of the Company shall then be closed or certificates representing such Conversion Shares shall not then have been actually delivered to the Holder. As soon as practicable and in any event within five (5) days after exercise of the Default Conversion Right, the Company shall issue and deliver to the Holder a certificate or certificates evidencing the Conversion Shares registered in the name of the Holder or its designee, provided that the Company may require the holder, by notice given to the Holder promptly after receipt of the Conversion Notice, as a condition to the delivery of such certificate or certificates, to present this Note to the Company for the placement hereon of a legend indicating that the Default Conversion Right has been exercised to the extent of the Default Conversion Amount, and this Note (unless thereby paid in full) shall be immediately returned to the Holder. Page 54 of 99 Pages (d) The issuance of any shares or other securities upon the exercise of the Default Conversion Right, and the delivery of certificates or other instruments representing such shares or other securities, shall be made without charge to the Holder for any tax or other charge in respect of such issuance. The Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of any certificate in a name other than that of the Holder and the Company shall not be required to issue or deliver any such certificate unless and until the person or persons requesting the issue thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. (e) The Holder shall not have, solely on account of such status as a Holder of this Note, any rights of a stockholder of the Company, either at law or in equity, or any notice of meetings of stockholders or of any other proceedings of the Company except as provided in this Note. (f) The Company shall at all times following the Issuance Date, reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose of providing for the exercise of the Default Conversion Right, such number of shares of Common Stock as shall, from time to time, be sufficient for the exercise of the Default Conversion Right in full. The Company covenants that all shares of Common Stock issuable upon exercise of the Default Conversion Right shall be validly issued, fully paid and nonassessable. (g) The anti-dilution protections set forth in Section 2(c) hereof shall apply as well to the Default Conversion Right and the adjustment of the Default Conversion Price hereunder, provided, however, that for purposes of such application all appropriate references to Preferred Stock shall be read as references to Common Stock and all references to the Conversion Price shall be read as references to the Default Conversion Price, so as to give the Default Conversion Rights, as nearly as practicable, the anti-dilution and other protections provided for in section 2(c) with respect to the Optional Conversion Right. SECTION 4. FRACTIONAL SHARES. (a) The Company shall not be required to issue fractions of shares of Common Stock or other capital stock of the Company upon the exercise of the Optional and Default Conversion Right. If any fraction of a share would be issuable on any exercise of the Optional or Default Conversion Right (or specified portions thereof), the Company shall purchase such fraction for an amount in cash equal to the same fraction of the closing price for the Common Stock on the trading date immediately preceding the date of exercise of the Optional or Default Conversion Right. SECTION 5. AFFIRMATIVE COVENANTS OF THE COMPANY. The Company covenants and agrees that until the payment in full of this Note, the Company shall: (a) Existence; Business.

(f) No Impairment. By amendment of its charter or through reorganization, consolidation, merger, dissolution, sale of assets or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Note, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Holder of this Note against impairment.

No fractional shares or scrip representing fractional shares shall be issued upon exercise of this Warrant; provided that the Company shall pay to the holders of the Warrant cash in lieu of such fractional shares. Page 61 of 99 Pages 2. RESERVATION OF WARRANT SHARES; FULLY PAID SHARES; TAXES. The Company hereby represents that it has, and until expiration of this Warrant agrees that it shall, reserve for issuance or delivery upon exercise of this Warrant, such number of shares of the Common Stock as shall be required for issuance and/or delivery upon exercise of this Warrant in full, and agrees that all Warrant Shares so issued and/or delivered will be validly issued, fully paid and non-assessable, and further agrees to pay all taxes and charges that may be imposed upon such issuance and/or delivery. 3. PROTECTION AGAINST DILUTION. (a) In the event the Company shall, at any time or from time to time after the date of issuance of this Warrant, issue or distribute to all of the holders of its shares of Common Stock evidence of its indebtedness, any other securities of the Company or any cash, property or other assets (any such event being herein called a "SPECIAL DIVIDEND"), the Per Share Exercise Price shall be adjusted by multiplying the Per Share Exercise Price then in effect by a fraction, the numerator of which shall be the then Current Market Price (as defined in paragraph 3(k) below) of the Common Stock, less the Current Market Price of the Special Dividend issued or distributed in respect of one share of Common Stock, and the denominator of which shall be the Current Market Price of the Common Stock. Such adjustment shall be made successively whenever such a record date is fixed. Such adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record date for the determination of shareholders entitled to receive such distribution. (b) In case the Company shall hereafter (i) pay a dividend or make a distribution on its capital stock in shares of Common Stock, (ii) subdivide its outstanding shares of Common Stock into a greater number of shares, (iii) combine its outstanding shares of Common Stock into a smaller number of shares or (iv) issue by reclassification of its Common Stock any shares of capital stock of the Company, the Per Share Exercise Price shall be adjusted to be equal to a fraction, the numerator of which shall be the Aggregate Exercise Price and the denominator of which shall be the number of shares of Common Stock or other capital stock of the Company issuable upon exercise of this Warrant assuming this Warrant had been exercised immediately prior to such action. An adjustment made pursuant to this subsection 3(b) shall become effective immediately after the record date in the case of a dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or reclassification. (c)(i) Except as provided in subsections 3(a) and 3(b)(i), in the event the Company shall hereafter issue or sell any Common Stock, any securities convertible into Common Stock or any rights, options or warrants to purchase Common Stock or securities convertible into Common Stock, in each case for a price per share or entitling the holders thereof to purchase Common Stock at a price per share (determined by dividing (i) the total amount, if any, received or receivable by the Company in consideration of the issuance or sale of such securities plus the consideration, if any, payable to the Company upon exercise or conversion thereof (collectively, the "TOTAL CONSIDERATION") by (ii) the number of additional shares of Common Stock issued, sold or issuable upon exercise or conversion of such securities) which is less than the then Current Market Price of the Common Stock (as defined below) but not below the current Per Share Exercise Price (which event is governed by subsection 3(c)(ii)), the Per Share Exercise Price shall be adjusted as of the date of such issuance or sale by multiplying the Per Share Exercise Price then in effect by a fraction, the numerator of which shall be (x) the sum of (A) the number of shares of Common Stock outstanding on the record date of such issuance or sale plus (B) the Total Consideration divided by the Current Market Price of the Common Stock, and the denominator of which shall be (y) the number of shares of Common Stock outstanding on the record date of such issuance or sale plus the maximum number of additional shares of Common Stock issued, sold or issuable upon exercise or conversion of such securities. (c)(ii) Except as provided in subsection 3(a) and 3(b)(i), in the event the Company shall hereafter issue or sell any Common Stock, any securities convertible into Common Stock or any rights, options or warrants to purchase Common Stock or securities convertible into Common Stock, in each case for a price per share or entitling the holders thereof to purchase Common Stock at a price per share (the "ISSUE PRICE"), (determined by dividing (i) the Total Consideration by (ii) the number of additional Page 62 of 99 Pages shares of Common Stock issuable upon exercise or conversion of such securities) which is less than the then current Per Share Exercise Price in effect on the record date of such issuance, the Per Share Exercise Price shall be adjusted to equal the Issue Price. (d) In the event of any capital reorganization or reclassification, or any consolidation or merger to which the Company is a party other than a merger or consolidation in which the Company is the continuing corporation, or in case of any sale or conveyance to another entity of the property of the Company as an entirety or substantially as an entirety, or in the case of any statutory exchange of securities with another corporation (including any exchange effected in connection with a merger of a third corporation into the Company), the Holder of this Warrant shall have the right thereafter to receive on the exercise of this Warrant the kind and amount of securities, cash or other property which the Holder would have owned or have been entitled to receive immediately after such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance had this Warrant been exercised immediately prior to the effective date of such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance and in any such case, if necessary, appropriate adjustment shall be made in the application of the provisions set forth in this Section 3 with respect to the rights and interests thereafter of the Holder of this Warrant to the end that the provisions set forth in this Section 3 shall thereafter correspondingly be made applicable, as nearly as may reasonably be, in relation to any shares of stock or other securities or property thereafter deliverable on the exercise of this Warrant. The above provisions of this subsection 3(e) shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, statutory exchanges, sales or conveyances. The issuer of any shares of stock or other securities or property thereafter deliverable on the exercise of this Warrant shall be responsible for all of the agreements and obligations of the Company hereunder. Notice of any such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance and of said provisions so proposed to be made, shall be mailed to the Holders of the Warrants not less than 30 days prior to such event. A sale of all or substantially all of the assets of the Company for a consideration consisting primarily of securities shall be deemed a consolidation or merger for the foregoing purposes. (e) In case any event shall occur as to which the other provisions of this Section 3 are not strictly applicable but as to which the failure to make any adjustment would not fairly protect the purchase rights represented by this Warrant in accordance with the essential intent and principles hereof then, in each such case, the Holders of Warrants representing the right to purchase a majority of the Warrant Shares subject to all outstanding Warrants may appoint a firm of independent public accountants of recognized national standing reasonably acceptable to the Company, which shall give their opinion as to the adjustment, if any, on a basis consistent with the essential intent and principles established herein, necessary to preserve the purchase rights represented by the Warrants. Upon receipt of such opinion, the Company will promptly mail a copy thereof to the Holder of this Warrant and shall make the adjustments described therein. The fees and expenses of such independent public accountants shall be borne by the Company. (f) Whenever the Per Share Exercise Price payable upon exercise of each Warrant is adjusted pursuant to this Section 3, the number of shares of Common Stock underlying a Warrant shall simultaneously be adjusted to equal the number obtained by dividing the Aggregate Exercise Price by the adjusted Per Share Exercise Price. (g) No adjustment in the Per Share Exercise Price shall be required unless such adjustment would require an increase or decrease of at least $0.01 per share of Common Stock; provided, however, that any adjustments which by reason of this subsection 3(g) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 3 shall be made to the nearest cent or to the nearest 1/100th of a share, as the case may be. Anything in this Section 3 to the contrary notwithstanding, the Company shall be entitled to make such reductions in the Per Share Exercise Price, in addition to those required by this Section 3, as it in its discretion shall deem to be advisable in order that any stock dividend, subdivision of shares or distribution of rights to purchase stock or securities convertible or exchangeable for stock hereafter made by the Company to its stockholders shall not be taxable. Page 63 of 99 Pages (h) Whenever the Per Share Exercise Price is adjusted as provided in this Section 3 and upon any modification of the rights of a Holder of Warrants in accordance with this Section 3, the Company shall promptly obtain, at its expense, a certificate of a firm of independent public accountants of recognized standing selected by the Board of Directors (who may be the regular auditors of the Company) setting forth the Per Share Exercise Price and the number of Warrant Shares after such adjustment or the effect of such modification, a brief statement of the facts requiring such adjustment or modification and the manner of computing the same and cause copies of such certificate to be mailed to the Holders of the Warrants. (i) If the Board of Directors of the Company shall declare any dividend or other distribution with respect to the Common Stock, the Company shall mail notice thereof to the Holders of the Warrants not less than 30 days prior to the record date fixed for determining stockholders entitled to participate in such dividend or other distribution. (j) If, as a result of an adjustment made pursuant to this Section 3, the Holder of any Warrant thereafter surrendered for exercise shall become entitled to receive shares of two or more classes of capital stock or shares of Common Stock and other capital stock of the Company, the Board of Directors (whose determination shall be conclusive and shall be described in a written notice to the Holder of any Warrant promptly after such adjustment) shall determine the allocation of the adjusted Per Share Exercise Price between or among shares or such classes of capital stock or shares of Common Stock and other capital stock. (k) For the purpose of any computation under Section 3 above, the then Current Market Price per share (the "CURRENT MARKET PRICE") shall be deemed to be the last sale price of the Common Stock on the trading day prior to such date or, in case no such reported sales take place on such day, the average of the last reported bid and asked prices of the Common Stock on such day, in either case on the principal national securities exchange on which the Common Stock is admitted to trading or listed, or if not listed or admitted to trading on any such exchange, the representative closing bid price of the Common Stock as reported by the National Association of Securities Dealers, Inc. Automated Quotations System ("NASDAQ"), or other similar organization if NASDAQ is no longer reporting such information, or, if the Common Stock is not reported on NASDAQ, the high per share bid price for the Common Stock in the over-the-counter market as reported by the National Quotation Bureau or similar organization, or if not so available, the fair market value of the Common Stock as determined by agreement between the Company's Board of Directors, on the one part, and the Holders of Warrants representing the right to purchase a majority of the Warrant Shares subject to all outstanding Warrants, on the second part. If the Board of Directors and such Holders fail to agree on the Current Market Price within 60 days of the date of the action giving rise to any adjustment pursuant to this Section 3, such Holders shall be entitled to appoint a firm of independent public accountants or appraisers of recognized national standing reasonably acceptable to the Company, which shall give their opinion as to such Current Market Price on a basis consistent with the essential intent and principles established herein. Upon receipt of such opinion, the Company will promptly mail a copy thereof to the Holder of this Warrant and shall make the adjustments described therein. The fees and expenses of such independent public accountants or appraisers shall be borne by the Company. 4. REGISTRATION UNDER SECURITIES ACT OF 1933. The resale of the Warrant Shares shall be registered on the Shelf Registration Statement (as defined in Article 8 of the Note and Warrant Purchase Agreement (the "Purchase Agreement") dated as of January 28, 1997, by and among the Company, The Aries Fund, a Cayman Island Trust, and The Aries Domestic Fund, L.P., a Delaware limited partnership) and certain purchasers and the Holder of this Warrant shall have the registration rights as provided in Article 8 of the Purchase Agreement. If the Holder is not a party to the Purchase Agreement, by acceptance of this Warrant the Holder agrees to comply with provisions of Article 8 of the Purchase Agreement to the same extent as if it were a party thereto. 5. LIMITED TRANSFERABILITY. This Warrant may not be sold, transferred, assigned or hypothecated by the Holder except in compliance with the provisions of the Act and the applicable state securities "blue sky" laws, and is so transferable only upon the books of the Company which it shall cause to be maintained for such purpose. The Company may treat the registered Holder of this Warrant as he or it appears on the Company's books Page 64 of 99 Pages at any time as the Holder for all purposes. The Company shall permit any Holder of a Warrant or his duly authorized attorney, upon written request during ordinary business hours, to inspect and copy or make extracts from its books showing the registered holders of Warrants. All Warrants issued upon the transfer or assignment of this Warrant will be dated the same date as this Warrant, and all rights of the holder thereof shall be identical to those of the Holder. 6. LOSS, ETC., OF WARRANT. Upon receipt of evidence satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant, and of indemnity reasonably satisfactory to the Company, if lost, stolen or destroyed, and upon surrender and cancellation of this Warrant, if mutilated, the Company shall execute and deliver to the Holder a new Warrant of like date, tenor and denomination. 7. STATUS OF HOLDER. This Warrant does not confer upon the Holder any right to vote or to consent to or receive notice as a stockholder of the Company, as such, in respect of any matters whatsoever, or any other rights or liabilities as a stockholder, prior to the exercise hereof. 8. NOTICES. No notice or other communication under this Warrant shall be effective unless, but any notice or other communication shall be effective and shall be deemed to have been given if, the same is in writing and is mailed by first-class mail, postage prepaid, addressed to: (a) the Company at 3550 General Atomic Corporation, San Diego, California 92121, Attention: Thomas H. Adams, or such other address as the Company has designated in writing to the Holder; or (b) the Holder at the address indicated in the notice provisions to the Purchase Agreement, or other such address as the Holder has designated in writing to the Company. 9. OPTIONAL CONVERSION. Each warrant shall be convertible into a New Warrant (as hereinafter defined) on a one for one basis. "New Warrants" shall mean a new class of warrants entitling the holders thereof to purchase, at any time on or before the date which is five (5) years from the date hereof, one share of Common Stock at an exercise price equal to the lesser of (a) $0.15, and (b) fifty percent (50%) of the average closing bid price of the Common Stock for either (i) the thirty (30) consecutive trading days immediately succeeding the date of the Required Shareholder Approval, if any (the "Approval Date"), or (ii) the five (5) consecutive trading days preceding the Approval Date if any. Other than the exercise price, the New Warrants shall have the same terms as the Class A Warrants. To the extent that there is no Required Shareholder Approval necessary the foregoing clause (b) shall ignored. Notwithstanding the foregoing, the New Warrants' exercise price shall be adjusted at the time of the Final Closing Date (as that term is defined in the Letter between Genta and Paramount Capital Inc., dated January 28, 1997) if the exercise price of the Offering Warrants (as defined below) is less than the exercise price of the New Warrants. In such event the New Warrants exercise price shall be reduced to equal 50% of the then current exercise price of the Offering Warrants (as hereafter defined). "Offering Warrants" shall mean the warrants described in paragraph 7 of the Letter between the Company and Paramount Capital, Inc. dated January 28, 1997. "Required Shareholder Approval" shall mean the authorization and approval by the holders of the Common Stock of the Company of the issuance of the shares of Common Stock underlying the Company's Senior Secured Convertible Bridge Notes, to the extent such authorization is required pursuant to the rules of the Nasdaq National Market or any other statute, rule or regulation. 10. HEADINGS. The headings of this Warrant have been inserted as a matter of convenience and shall not affect the construction hereof. 11. APPLICABLE LAW. This Warrant shall be governed by and construed in accordance with the law of the State of New York without giving effect to principles of conflicts of law thereof.

GENTA INCORPORATED Class A Bridge Warrant for the Purchase of Shares of Common Stock No. CA-2 5,070,000 Shares FOR VALUE RECEIVED, GENTA INCORPORATED., a Delaware corporation (the "COMPANY"), hereby certifies that THE ARIES TRUST or its registered assigns (the "Holder") is entitled to purchase from the Company, subject to the provisions of this Warrant (the "Warrant"), at any time commencing upon the date hereof (the "INITIAL EXERCISE DATE"), and prior to 5:00 P.M., New York City time, on the date which is five (5) years from the date hereof (the "TERMINATION DATE"), 5,070,000 fully paid and non-assessable shares of the Common Stock, $.001 par value, of the Company ("Common Stock"), at an exercise price of $0.001 per share of Common Stock for an aggregate exercise price of FIVE THOUSAND SEVENTY DOLLARS ($5,070.00) (the aggregate purchase price payable for the Warrant Shares hereunder is hereinafter sometimes referred to as the "AGGREGATE EXERCISE PRICE"). The number of shares of Common Stock to be received upon exercise of this Warrant and the price to be paid for each share of Common Stock are subject to possible adjustment from time to time as hereinafter set forth. The shares of Common Stock or other securities or property deliverable upon such exercise as adjusted from time to time is hereinafter sometimes referred to as the "WARRANT SHARES." The exercise price of a share of Common Stock in effect at any time and as adjusted from time to time is hereinafter sometimes referred to as the "PER SHARE EXERCISE PRICE." The Per Share Exercise Price is subject to adjustment as hereinafter provided; in the event of any such adjustment, the number of Warrant Shares shall be adjusted by dividing the Aggregate Exercise Price by the Per Share Exercise Price in effect immediately after such adjustment. The Aggregate Exercise Price is not subject to adjustment. 1. EXERCISE OF WARRANT. (a) This Warrant may be exercised in whole or in part, at any time by the Holder commencing on the Initial Exercise Date and prior to the Termination Date, by presentation and surrender of this Warrant, together with the duly executed subscription form attached at the end hereof, at the address set forth in subsection 8(a) hereof, together with payment, by certified or official bank check or wire transfer payable to the order of the Company, of the Aggregate Exercise Price or the proportionate part thereof if exercised in part. (b) If this Warrant is exercised in part only, the Company shall, upon presentation of this Warrant upon such exercise, execute and deliver (along with the certificate for the Warrant Shares purchased) a new Warrant evidencing the rights of the Holder hereof to purchase the balance of the Warrant Shares purchasable hereunder upon the same terms and conditions as herein set forth. Upon proper exercise of this Warrant, the Company promptly shall deliver certificates for the Warrant Shares to the Holder duly legended as authorized by the subscription form. No fractional shares or scrip representing fractional shares shall be issued upon exercise of this Warrant; provided that the Company shall pay to the holders of the Warrant cash in lieu of such fractional shares. Page 68 of 99 Pages 2. RESERVATION OF WARRANT SHARES; FULLY PAID SHARES; TAXES. The Company hereby represents that it has, and until expiration of this Warrant agrees that it shall, reserve for issuance or delivery upon exercise of this Warrant, such number of shares of the Common Stock as shall be required for issuance and/or delivery upon exercise of this Warrant in full, and agrees that all Warrant Shares so issued and/or delivered will be validly issued, fully paid and non-assessable, and further agrees to pay all taxes and charges that may be imposed upon such issuance and/or delivery. 3. PROTECTION AGAINST DILUTION. (a) In the event the Company shall, at any time or from time to time after the date of issuance of this Warrant, issue or distribute to all of the holders of its shares of Common Stock evidence of its indebtedness, any other securities of the Company or any cash, property or other assets (any such event being herein called a "SPECIAL DIVIDEND"), the Per Share Exercise Price shall be adjusted by multiplying the Per Share Exercise Price then in effect by a fraction, the numerator of which shall be the then Current Market Price (as defined in paragraph 3(k) below) of the Common Stock, less the Current Market Price of the Special Dividend issued or distributed in respect of one share of Common Stock, and the denominator of which shall be the Current Market Price of the Common Stock. Such adjustment shall be made successively whenever such a record date is fixed. Such adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record date for the determination of shareholders entitled to receive such distribution. (b) In case the Company shall hereafter (i) pay a dividend or make a distribution on its capital stock in shares of Common Stock, (ii) subdivide its outstanding shares of Common Stock into a greater number of shares, (iii) combine its outstanding shares of Common Stock into a smaller number of shares or (iv) issue by reclassification of its Common Stock any shares of capital stock of the Company, the Per Share Exercise Price shall be adjusted to be equal to a fraction, the numerator of which shall be the Aggregate Exercise Price and the denominator of which shall be the number of shares of Common Stock or other capital stock of the Company issuable upon exercise of this Warrant assuming this Warrant had been exercised immediately prior to such action. An adjustment made pursuant to this subsection 3(b) shall become effective immediately after the record date in the case of a dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or reclassification. (c)(i) Except as provided in subsections 3(a) and 3(b)(i), in the event the Company shall hereafter issue or sell any Common Stock, any securities convertible into Common Stock or any rights, options or warrants to purchase Common Stock or securities convertible into Common Stock, in each case for a price per share or entitling the holders thereof to purchase Common Stock at a price per share (determined by dividing (i) the total amount, if any, received or receivable by the Company in consideration of the issuance or sale of such securities plus the consideration, if any, payable to the Company upon exercise or conversion thereof (collectively, the "TOTAL CONSIDERATION") by (ii) the number of additional shares of Common Stock issued, sold or issuable upon exercise or conversion of such securities) which is less than the then Current Market Price of the Common Stock (as defined below) but not below the current Per Share Exercise Price (which event is governed by subsection 3(c)(ii)), the Per Share Exercise Price shall be adjusted as of the date of such issuance or sale by multiplying the Per Share Exercise Price then in effect by a fraction, the numerator of which shall be (x) the sum of (A) the number of shares of Common Stock outstanding on the record date of such issuance or sale plus (B) the Total Consideration divided by the Current Market Price of the Common Stock, and the denominator of which shall be (y) the number of shares of Common Stock outstanding on the record date of such issuance or sale plus the maximum number of additional shares of Common Stock issued, sold or issuable upon exercise or conversion of such securities. (c)(ii) Except as provided in subsection 3(a) and 3(b)(i), in the event the Company shall hereafter issue or sell any Common Stock, any securities convertible into Common Stock or any rights, options or warrants to purchase Common Stock or securities convertible into Common Stock, in each case for a price per share or entitling the holders thereof to purchase Common Stock at a price per share (the "ISSUE PRICE"), (determined by dividing (i) the Total Consideration by (ii) the number of additional Page 69 of 99 Pages shares of Common Stock issuable upon exercise or conversion of such securities) which is less than the then current Per Share Exercise Price in effect on the record date of such issuance, the Per Share Exercise Price shall be adjusted to equal the Issue Price. (d) In the event of any capital reorganization or reclassification, or any consolidation or merger to which the Company is a party other than a merger or consolidation in which the Company is the continuing corporation, or in case of any sale or conveyance to another entity of the property of the Company as an entirety or substantially as an entirety, or in the case of any statutory exchange of securities with another corporation (including any exchange effected in connection with a merger of a third corporation into the Company), the Holder of this Warrant shall have the right thereafter to receive on the exercise of this Warrant the kind and amount of securities, cash or other property which the Holder would have owned or have been entitled to receive immediately after such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance had this Warrant been exercised immediately prior to the effective date of such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance and in any such case, if necessary, appropriate adjustment shall be made in the application of the provisions set forth in this Section 3 with respect to the rights and interests thereafter of the Holder of this Warrant to the end that the provisions set forth in this Section 3 shall thereafter correspondingly be made applicable, as nearly as may reasonably be, in relation to any shares of stock or other securities or property thereafter deliverable on the exercise of this Warrant. The above provisions of this subsection 3(e) shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, statutory exchanges, sales or conveyances. The issuer of any shares of stock or other securities or property thereafter deliverable on the exercise of this Warrant shall be responsible for all of the agreements and obligations of the Company hereunder. Notice of any such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance and of said provisions so proposed to be made, shall be mailed to the Holders of the Warrants not less than 30 days prior to such event. A sale of all or substantially all of the assets of the Company for a consideration consisting primarily of securities shall be deemed a consolidation or merger for the foregoing purposes. (e) In case any event shall occur as to which the other provisions of this Section 3 are not strictly applicable but as to which the failure to make any adjustment would not fairly protect the purchase rights represented by this Warrant in accordance with the essential intent and principles hereof then, in each such case, the Holders of Warrants representing the right to purchase a majority of the Warrant Shares subject to all outstanding Warrants may appoint a firm of independent public accountants of recognized national standing reasonably acceptable to the Company, which shall give their opinion as to the adjustment, if any, on a basis consistent with the essential intent and principles established herein, necessary to preserve the purchase rights represented by the Warrants. Upon receipt of such opinion, the Company will promptly mail a copy thereof to the Holder of this Warrant and shall make the adjustments described therein. The fees and expenses of such independent public accountants shall be borne by the Company. (f) Whenever the Per Share Exercise Price payable upon exercise of each Warrant is adjusted pursuant to this Section 3, the number of shares of Common Stock underlying a Warrant shall simultaneously be adjusted to equal the number obtained by dividing the Aggregate Exercise Price by the adjusted Per Share Exercise Price. (g) No adjustment in the Per Share Exercise Price shall be required unless such adjustment would require an increase or decrease of at least $0.01 per share of Common Stock; provided, however, that any adjustments which by reason of this subsection 3(g) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 3 shall be made to the nearest cent or to the nearest 1/100th of a share, as the case may be. Anything in this Section 3 to the contrary notwithstanding, the Company shall be entitled to make such reductions in the Per Share Exercise Price, in addition to those required by this Section 3, as it in its discretion shall deem to be advisable in order that any stock dividend, subdivision of shares or distribution of rights to purchase stock or securities convertible or exchangeable for stock hereafter made by the Company to its stockholders shall not be taxable. Page 70 of 99 Pages (h) Whenever the Per Share Exercise Price is adjusted as provided in this Section 3 and upon any modification of the rights of a Holder of Warrants in accordance with this Section 3, the Company shall promptly obtain, at its expense, a certificate of a firm of independent public accountants of recognized standing selected by the Board of Directors (who may be the regular auditors of the Company) setting forth the Per Share Exercise Price and the number of Warrant Shares after such adjustment or the effect of such modification, a brief statement of the facts requiring such adjustment or modification and the manner of computing the same and cause copies of such certificate to be mailed to the Holders of the Warrants. (i) If the Board of Directors of the Company shall declare any dividend or other distribution with respect to the Common Stock, the Company shall mail notice thereof to the Holders of the Warrants not less than 30 days prior to the record date fixed for determining stockholders entitled to participate in such dividend or other distribution. (j) If, as a result of an adjustment made pursuant to this Section 3, the Holder of any Warrant thereafter surrendered for exercise shall become entitled to receive shares of two or more classes of capital stock or shares of Common Stock and other capital stock of the Company, the Board of Directors (whose determination shall be conclusive and shall be described in a written notice to the Holder of any Warrant promptly after such adjustment) shall determine the allocation of the adjusted Per Share Exercise Price between or among shares or such classes of capital stock or shares of Common Stock and other capital stock. (k) For the purpose of any computation under Section 3 above, the then Current Market Price per share (the "CURRENT MARKET PRICE") shall be deemed to be the last sale price of the Common Stock on the trading day prior to such date or, in case no such reported sales take place on such day, the average of the last reported bid and asked prices of the Common Stock on such day, in either case on the principal national securities exchange on which the Common Stock is admitted to trading or listed, or if not listed or admitted to trading on any such exchange, the representative closing bid price of the Common Stock as reported by the National Association of Securities Dealers, Inc. Automated Quotations System ("NASDAQ"), or other similar organization if NASDAQ is no longer reporting such information, or, if the Common Stock is not reported on NASDAQ, the high per share bid price for the Common Stock in the over-the-counter market as reported by the National Quotation Bureau or similar organization, or if not so available, the fair market value of the Common Stock as determined by agreement between the Company's Board of Directors, on the one part, and the Holders of Warrants representing the right to purchase a majority of the Warrant Shares subject to all outstanding Warrants, on the second part. If the Board of Directors and such Holders fail to agree on the Current Market Price within 60 days of the date of the action giving rise to any adjustment pursuant to this Section 3, such Holders shall be entitled to appoint a firm of independent public accountants or appraisers of recognized national standing reasonably acceptable to the Company, which shall give their opinion as to such Current Market Price on a basis consistent with the essential intent and principles established herein. Upon receipt of such opinion, the Company will promptly mail a copy thereof to the Holder of this Warrant and shall make the adjustments described therein. The fees and expenses of such independent public accountants or appraisers shall be borne by the Company. 4. REGISTRATION UNDER SECURITIES ACT OF 1933. The resale of the Warrant Shares shall be registered on the Shelf Registration Statement (as defined in Article 8 of the Note and Warrant Purchase Agreement (the "Purchase Agreement") dated as of January 28, 1997, by and among the Company, The Aries Fund, a Cayman Island Trust, and The Aries Domestic Fund, L.P., a Delaware limited partnership) and certain purchasers and the Holder of this Warrant shall have the registration rights as provided in Article 8 of the Purchase Agreement. If the Holder is not a party to the Purchase Agreement, by acceptance of this Warrant the Holder agrees to comply with provisions of Article 8 of the Purchase Agreement to the same extent as if it were a party thereto. 5. LIMITED TRANSFERABILITY. This Warrant may not be sold, transferred, assigned or hypothecated by the Holder except in compliance with the provisions of the Act and the applicable state securities "blue sky" laws, and is so transferable only upon the books of the Company which it shall cause to be maintained for such purpose.

STATUS OF HOLDER. This Warrant does not confer upon the Holder any right to vote or to consent to or receive notice as a stockholder of the Company, as such, in respect of any matters whatsoever, or any other rights or liabilities as a stockholder, prior to the exercise hereof. 8.

OPTIONAL CONVERSION. Each warrant shall be convertible into a New Warrant (as hereinafter defined) on a one for one basis. "New Warrants" shall mean a new class of warrants entitling the holders thereof to purchase, at any time on or before the date which is five (5) years from the date hereof, one share of Common Stock at an exercise price equal to the lesser of (a) $0.15, and (b) fifty percent (50%) of the average closing bid price of the Common Stock for either (i) the thirty (30) consecutive trading days immediately succeeding the date of the Required Shareholder Approval, if any (the "Approval Date"), or (ii) the five (5) consecutive trading days preceding the Approval Date, if any. Other than the exercise price, the New Warrants shall have the same terms as the Class A Warrants. To the extent that there is no Required Shareholder Approval necessary the foregoing clause (b) shall be ignored. Notwithstanding the foregoing, the New Warrants' exercise price shall be adjusted at the time of the Final Closing Date (as that term is defined in the Letter between Genta and Paramount Capital Inc., dated January 28, 1997) if the exercise price of the Offering Warrants (as defined below) is less than the exercise price of the New Warrants. In such event the New Warrants exercise price shall be reduced to equal 50% of the then current exercise price of the Offering Warrants (as hereafter defined). "Offering Warrants" shall mean the warrants described in paragraph 7 of the Letter between the Company and Paramount Capital, Inc. dated January 28, 1997. "Required Shareholder Approval" shall mean the authorization and approval by the holders of the Common Stock of the Company of the issuance of the shares of Common Stock underlying the Company's Senior Secured Convertible Bridge Notes, to the extent such authorization is required pursuant to the rules of the Nasdaq National Market or any other statute, rule or regulation. 10.

GENTA INCORPORATED Class B Bridge Warrant for the Purchase of Shares of Common Stock No. CB-1 4,270,000 Shares FOR VALUE RECEIVED, GENTA INCORPORATED., a Delaware corporation (the "COMPANY"), hereby certifies that THE ARIES DOMESTIC FUND, LP, or its registered assigns (the "Holder") is entitled to purchase from the Company, subject to the provisions of this Warrant (the "Warrant"), at any time commencing upon the date hereof (the "INITIAL EXERCISE DATE"), and prior to 5:00 P.M., New York City time, on the date which is five (5) years from the date hereof (the "TERMINATION DATE"), 4,270,000 fully paid and non-assessable shares of the Common Stock, $.001 par value, of the Company ("Common Stock"), at an exercise price equal to $.55 per share of Common Stock for an aggregate exercise price of TWO MILLION THREE HUNDRED FORTY EIGHT THOUSAND FIVE HUNDRED DOLLARS ($2,348,500.00) (the aggregate purchase price payable for the Warrant Shares hereunder is hereinafter sometimes referred to as the "AGGREGATE EXERCISE PRICE"). The number of shares of Common Stock to be received upon exercise of this Warrant and the price to be paid for each share of Common Stock are subject to possible adjustment from time to time as hereinafter set forth. The shares of Common Stock or other securities or property deliverable upon such exercise as adjusted from time to time is hereinafter sometimes referred to as the "WARRANT SHARES." The exercise price of a share of Common Stock in effect at any time and as adjusted from time to time is hereinafter sometimes referred to as the "PER SHARE EXERCISE PRICE." The Per Share Exercise Price is subject to adjustment as hereinafter provided; in the event of any such adjustment, the number of Warrant Shares shall be adjusted by dividing the Aggregate Exercise Price by the Per Share Exercise Price in effect immediately after such adjustment. The Aggregate Exercise Price is not subject to adjustment. 1. EXERCISE OF WARRANT. (a) This Warrant may be exercised in whole or in part, at any time by the Holder commencing on the Initial Exercise Date and prior to the Termination Date, by presentation and surrender of this Warrant, together with the duly executed subscription form attached at the end hereof, at the address set forth in subsection 8(a) hereof, together with payment, by certified or official bank check or wire transfer payable to the order of the Company, of the Aggregate Exercise Price or the proportionate part thereof if exercised in part. (b) If this Warrant is exercised in part only, the Company shall, upon presentation of this Warrant upon such exercise, execute and deliver (along with the certificate for the Warrant Shares purchased) a new Warrant evidencing the rights of the Holder hereof to purchase the balance of the Warrant Shares purchasable hereunder upon the same terms and conditions as herein set forth. Upon proper exercise of this Warrant, the Company promptly shall deliver certificates for the Warrant Shares to the Holder duly legended as authorized by the subscription form. No fractional shares or scrip representing fractional shares shall be issued upon exercise of this Warrant; provided Page 75 of 99 Pages that the Company shall pay to the holders of the Warrant cash in lieu of such fractional shares. 2. RESERVATION OF WARRANT SHARES; FULLY PAID SHARES; TAXES. The Company hereby represents that it has, and until expiration of this Warrant agrees that it shall, reserve for issuance or delivery upon exercise of this Warrant, such number of shares of the Common Stock as shall be required for issuance and/or delivery upon exercise of this Warrant in full, and agrees that all Warrant Shares so issued and/or delivered will be validly issued, fully paid and non-assessable, and further agrees to pay all taxes and charges that may be imposed upon such issuance and/or delivery. 3. PROTECTION AGAINST DILUTION. (a) In the event the Company shall, at any time or from time to time after the date of issuance of this Warrant, issue or distribute to all of the holders of its shares of Common Stock evidence of its indebtedness, any other securities of the Company or any cash, property or other assets (any such event being herein called a "SPECIAL DIVIDEND"), the Per Share Exercise Price shall be adjusted by multiplying the Per Share Exercise Price then in effect by a fraction, the numerator of which shall be the then Current Market Price (as defined in paragraph 3(k) below) of the Common Stock, less the Current Market Price of the Special Dividend issued or distributed in respect of one share of Common Stock, and the denominator of which shall be the Current Market Price of the Common Stock. Such adjustment shall be made successively whenever such a record date is fixed. Such adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record date for the determination of shareholders entitled to receive such distribution. (b) In case the Company shall hereafter (i) pay a dividend or make a distribution on its capital stock in shares of Common Stock, (ii) subdivide its outstanding shares of Common Stock into a greater number of shares, (iii) combine its outstanding shares of Common Stock into a smaller number of shares or (iv) issue by reclassification of its Common Stock any shares of capital stock of the Company, the number of shares to be delivered upon exercise of any share of this Warrant will be appropriately increased so that each Warrant holder thereafter will be entitled to receive the number of Common Shares that such holder would have owned immediately following such action had such Warrant been exercised immediately prior thereto, and the Per Share Exercise Price will be appropriately adjusted. An adjustment made pursuant to this subsection 3(b) shall become effective immediately after the record date in the case of a dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or reclassification. (c)(i) Except as provided in subsections 3(a) and 3(b)(i), in the event the Company shall hereafter issue or sell any Common Stock, any securities convertible into Common Stock or any rights, options or warrants to purchase Common Stock or securities convertible into Common Stock, in each case for a price per share or entitling the holders thereof to purchase Common Stock at a price per share (determined by dividing (i) the total amount, if any, received or receivable by the Company in consideration of the issuance or sale of such securities plus the consideration, if any, payable to the Company upon exercise or conversion thereof (collectively, the "TOTAL CONSIDERATION") by (ii) the number of additional shares of Common Stock issued, sold or issuable upon exercise or conversion of such securities) which is less than the then Current Market Price of the Common Stock (as defined below) but not below the current Per Share Exercise Price (which event is governed by subsection 3(c)(ii)), the Per Share Exercise Price shall be adjusted as of the date of such issuance or sale by multiplying the Per Share Exercise Price then in effect by a fraction, the numerator of which shall be (x) the sum of (A) the number of shares of Common Stock outstanding on the record date of such issuance or sale plus (B) the Total Consideration divided by the Current Market Price of the Common Stock, and the denominator of which shall be (y) the number of shares of Common Stock outstanding on the record date of such issuance or sale plus the maximum number of additional shares of Common Stock issued, sold or issuable upon exercise or conversion of such securities. (c)(ii) Except as provided in subsection 3(a) and 3(b)(i), in the event the Company shall hereafter issue or sell any Common Stock, any securities convertible into Common Stock or any rights, options or warrants to purchase Common Stock or Page 76 of 99 Pages securities convertible into Common Stock, in each case for a price per share or entitling the holders thereof to purchase Common Stock at a price per share (the "ISSUE PRICE"), (determined by dividing (i) the Total Consideration by (ii) the number of additional shares of Common Stock issuable upon exercise or conversion of such securities) which is less than the then current Per Share Exercise Price in effect on the record date of such issuance, the Per Share Exercise Price shall be adjusted to equal the Issue Price. (d) In the event of any capital reorganization or reclassification, or any consolidation or merger to which the Company is a party other than a merger or consolidation in which the Company is the continuing corporation, or in case of any sale or conveyance to another entity of the property of the Company as an entirety or substantially as an entirety, or in the case of any statutory exchange of securities with another corporation (including any exchange effected in connection with a merger of a third corporation into the Company), the Holder of this Warrant shall have the right thereafter to receive on the exercise of this Warrant the kind and amount of securities, cash or other property which the Holder would have owned or have been entitled to receive immediately after such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance had this Warrant been exercised immediately prior to the effective date of such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance and in any such case, if necessary, appropriate adjustment shall be made in the application of the provisions set forth in this Section 3 with respect to the rights and interests thereafter of the Holder of this Warrant to the end that the provisions set forth in this Section 3 shall thereafter correspondingly be made applicable, as nearly as may reasonably be, in relation to any shares of stock or other securities or property thereafter deliverable on the exercise of this Warrant. The above provisions of this subsection 3(e) shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, statutory exchanges, sales or conveyances. The issuer of any shares of stock or other securities or property thereafter deliverable on the exercise of this Warrant shall be responsible for all of the agreements and obligations of the Company hereunder. Notice of any such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance and of said provisions so proposed to be made, shall be mailed to the Holders of the Warrants not less than 30 days prior to such event. A sale of all or substantially all of the assets of the Company for a consideration consisting primarily of securities shall be deemed a consolidation or merger for the foregoing purposes. (e) In case any event shall occur as to which the other provisions of this Section 3 are not strictly applicable but as to which the failure to make any adjustment would not fairly protect the purchase rights represented by this Warrant in accordance with the essential intent and principles hereof then, in each such case, the Holders of Warrants representing the right to purchase a majority of the Warrant Shares subject to all outstanding Warrants may appoint a firm of independent public accountants of recognized national standing reasonably acceptable to the Company, which shall give their opinion as to the adjustment, if any, on a basis consistent with the essential intent and principles established herein, necessary to preserve the purchase rights represented by the Warrants. Upon receipt of such opinion, the Company will promptly mail a copy thereof to the Holder of this Warrant and shall make the adjustments described therein. The fees and expenses of such independent public accountants shall be borne by the Company. (f) Whenever the Per Share Exercise Price payable upon exercise of each Warrant is adjusted pursuant to this Section 3, the number of shares of Common Stock underlying a Warrant shall simultaneously be adjusted to equal the number obtained by dividing the Aggregate Exercise Price by the adjusted Per Share Exercise Price. (g) No adjustment in the Per Share Exercise Price shall be required unless such adjustment would require an increase or decrease of at least $0.01 per share of Common Stock; provided, however, that any adjustments which by reason of this subsection 3(g) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 3 shall be made to the nearest cent or to the nearest 1/100th of a share, as the case may be. Anything in this Section 3 to the contrary notwithstanding, the Company shall be entitled to make such reductions in the Per Share Exercise Price, in addition to those required by this Section 3, as it in its discretion shall deem to be advisable in order that any stock dividend, subdivision of shares or distribution of rights to purchase stock or securities convertible or Page 77 of 99 Pages exchangeable for stock hereafter made by the Company to its stockholders shall not be taxable. (h) Whenever the Per Share Exercise Price is adjusted as provided in this Section 3 and upon any modification of the rights of a Holder of Warrants in accordance with this Section 3, the Company shall promptly obtain, at its expense, a certificate of a firm of independent public accountants of recognized standing selected by the Board of Directors (who may be the regular auditors of the Company) setting forth the Per Share Exercise Price and the number of Warrant Shares after such adjustment or the effect of such modification, a brief statement of the facts requiring such adjustment or modification and the manner of computing the same and cause copies of such certificate to be mailed to the Holders of the Warrants. (i) If the Board of Directors of the Company shall declare any dividend or other distribution with respect to the Common Stock, the Company shall mail notice thereof to the Holders of the Warrants not less than 30 days prior to the record date fixed for determining stockholders entitled to participate in such dividend or other distribution. (j) If, as a result of an adjustment made pursuant to this Section 3, the Holder of any Warrant thereafter surrendered for exercise shall become entitled to receive shares of two or more classes of capital stock or shares of Common Stock and other capital stock of the Company, the Board of Directors (whose determination shall be conclusive and shall be described in a written notice to the Holder of any Warrant promptly after such adjustment) shall determine the allocation of the adjusted Per Share Exercise Price between or among shares or such classes of capital stock or shares of Common Stock and other capital stock. (k) For the purpose of any computation under Section 3 above, the then Current Market Price per share (the "CURRENT MARKET PRICE") shall be deemed to be the last sale price of the Common Stock on the trading day prior to such date or, in case no such reported sales take place on such day, the average of the last reported bid and asked prices of the Common Stock on such day, in either case on the principal national securities exchange on which the Common Stock is admitted to trading or listed, or if not listed or admitted to trading on any such exchange, the representative closing bid price of the Common Stock as reported by the National Association of Securities Dealers, Inc. Automated Quotations System ("NASDAQ"), or other similar organization if NASDAQ is no longer reporting such information, or, if the Common Stock is not reported on NASDAQ, the high per share bid price for the Common Stock in the over-the-counter market as reported by the National Quotation Bureau or similar organization, or if not so available, the fair market value of the Common Stock as determined by agreement between the Company's Board of Directors, on the one part, and the Holders of Warrants representing the right to purchase a majority of the Warrant Shares subject to all outstanding Warrants, on the second part. If the Board of Directors and such Holders fail to agree on the Current Market Price within 60 days of the date of the action giving rise to any adjustment pursuant to this Section 3, such Holders shall be entitled to appoint a firm of independent public accountants or appraisers of recognized national standing reasonably acceptable to the Company, which shall give their opinion as to such Current Market Price on a basis consistent with the essential intent and principles established herein. Upon receipt of such opinion, the Company will promptly mail a copy thereof to the Holder of this Warrant and shall make the adjustments described therein. The fees and expenses of such independent public accountants or appraisers shall be borne by the Company. 4. REGISTRATION UNDER SECURITIES ACT OF 1933. The resale of the Warrant Shares shall be registered on the Shelf Registration Statement (as defined in Article 8 of the Note and Warrant Purchase Agreement (the "Purchase Agreement") dated as of January 28, 1997, by and among the Company, The Aries Fund, a Cayman Island Trust, and The Aries Domestic Fund, L.P., a Delaware limited partnership) and certain purchasers and the Holder of this Warrant shall have the registration rights as provided in Article 8 of the Purchase Agreement. If the Holder is not a party to the Purchase Agreement, by acceptance of this Warrant the Holder agrees to comply with provisions of Article 8 of the Purchase Agreement to the same extent as if it were a party thereto. 5.

STATUS OF HOLDER. This Warrant does not confer upon the Holder any right to vote or to consent to or receive notice as a stockholder of the Company, as such, in respect of any matters whatsoever, or any other rights or liabilities as a stockholder, prior to the exercise hereof. 8. NOTICES.

Adams, or such other address as the Company has designated in writing to the Holder; or (b) the Holder at the address indicated in the notice provisions to the Purchase Agreement, or other such address as the Holder has designated in writing to the Company. 9. OPTIONAL CONVERSION. Each warrant shall be convertible into a New Warrant (as hereinafter defined) on a one for one basis. "New Warrants" shall mean a new class of warrants entitling the holders thereof to purchase, at any time on or before the date which is five (5) years from the date hereof, one share of Common Stock at an exercise price equal to the lesser of (a) $0.15, and (b) fifty percent (50%) of the average closing bid price of the Common Stock for either (i) the thirty (30) consecutive trading days immediately succeeding the date of the Required Shareholder Approval, if any (the "Approval Date"), or (ii) the five (5) consecutive trading days preceding the Approval Date, if any. Other than the exercise price, the New Warrants shall have the same terms as the Class A Warrants. To the extent that there is no Required Shareholder Approval necessary the foregoing clause (b) shall be ignored. Notwithstanding the foregoing, the New Warrants' exercise price shall be adjusted at the time of the Final Closing Date (as that term is defined in the Letter between Genta and Paramount Capital Inc., dated January 28, 1997) if the exercise price of the Offering Warrants (as defined below) is less than the exercise price of the New Warrants. In such event the New Warrants exercise price shall be reduced to equal 50% of the then current exercise price of the Offering Warrants (as hereafter defined). "Offering Warrants" shall mean the warrants described in paragraph 7 of the Letter between the Company and Paramount Capital, Inc. dated January 28, 1997.

The number of shares of Common Stock to be received upon exercise of this Warrant and the price to be paid for each share of Common Stock are subject to possible adjustment from time to time as hereinafter set forth. The shares of Common Stock or other securities or property deliverable upon such exercise as adjusted from time to time is hereinafter sometimes referred to as the "WARRANT SHARES." The exercise price of a share of Common Stock in effect at any time and as adjusted from time to time is hereinafter sometimes referred to as the "PER SHARE EXERCISE PRICE." The Per Share Exercise Price is subject to adjustment as hereinafter provided; in the event of any such adjustment, the number of Warrant Shares shall be adjusted by dividing the Aggregate Exercise Price by the Per Share Exercise Price in effect immediately after such adjustment.

(a) This Warrant may be exercised in whole or in part, at any time by the Holder commencing on the Initial Exercise Date and prior to the Termination Date, by presentation and surrender of this Warrant, together with the duly executed subscription form attached at the end hereof, at the address set forth in subsection 8(a) hereof, together with payment, by certified or official bank check or wire transfer payable to the order of the Company, of the Aggregate Exercise Price or the proportionate part thereof if exercised in part.

Upon proper exercise of this Warrant, the Company promptly shall deliver certificates for the Warrant Shares to the Holder duly legended as authorized by the subscription form.

The Company hereby represents that it has, and until expiration of this Warrant agrees that it shall, reserve for issuance or delivery upon exercise of this Warrant, such number of shares of the Common Stock as shall be required for issuance and/or delivery upon exercise of this Warrant in full, and agrees that all Warrant Shares so issued and/or delivered will be validly issued, fully paid and non-assessable, and further agrees to pay all taxes and charges that may be imposed upon such issuance and/or delivery. 3. PROTECTION AGAINST DILUTION. (a) In the event the Company shall, at any time or from time to time after the date of issuance of this Warrant, issue or distribute to all of the holders of its shares of Common Stock evidence of its indebtedness, any other securities of the Company or any cash, property or other assets (any such event being herein called a "SPECIAL DIVIDEND"), the Per Share Exercise Price shall be adjusted by multiplying the Per Share Exercise Price then in effect by a fraction, the numerator of which shall be the then Current Market Price (as defined in paragraph 3(k) below) of the Common Stock, less the Current Market Price of the Special Dividend issued or distributed in respect of one share of Common Stock, and the denominator of which shall be the Current Market Price of the Common Stock. Such adjustment shall be made successively whenever such a record date is fixed. Such adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record date for the determination of shareholders entitled to receive such distribution. (b) In case the Company shall hereafter (i) pay a dividend or make a distribution on its capital stock in shares of Common Stock, (ii) subdivide its outstanding shares of Common Stock into a greater number of shares, (iii) combine its outstanding shares of Common Stock into a smaller number of shares or (iv) issue by reclassification of its Common Stock any shares of capital stock of the Company, the Per Share Exercise Price shall be adjusted to be equal to a fraction, the numerator of which shall be the Aggregate Exercise Price and the denominator of which shall be the number of shares of Common Stock or other capital stock of the Company issuable upon exercise of this Warrant assuming this Warrant had been exercised immediately prior to such action. An adjustment made pursuant to this subsection 3(b) shall become effective immediately after the record date in the case of a dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or reclassification. (c)(i) Except as provided in subsections 3(a) and 3(b)(i), in the event the Company shall hereafter issue or sell any Common Stock, any securities convertible into Common Stock or any rights, options or warrants to purchase Common Stock or securities convertible into Common Stock, in each case for a price per share or entitling the holders thereof to purchase Common Stock at a price per share (determined by dividing (i) the total amount, if any, received or receivable by the Company in consideration of the issuance or sale of such securities plus the consideration, if any, payable to the Company upon exercise or conversion thereof (collectively, the "TOTAL CONSIDERATION") by (ii) the number of additional shares of Common Stock issued, sold or issuable upon exercise or conversion of such securities) which is less than the then Current Market Price of the Common Stock (as defined below) but not below the current Per Share Exercise Price (which event is governed by subsection 3(c)(ii)), the Per Share Exercise Price shall be adjusted as of the date of such issuance or sale by multiplying the Per Share Exercise Price then in effect by a fraction, the numerator of which shall be (x) the sum of (A) the number of shares of Common Stock outstanding on the record date of such issuance or sale plus (B) the Total Consideration divided by the Current Market Price of the Common Stock, and the denominator of which shall be (y) the number of shares of Common Stock outstanding on the record date of such issuance or sale plus the maximum number of additional shares of Common Stock issued, sold or issuable upon exercise or conversion of such securities. (c)(ii) Except as provided in subsection 3(a) and 3(b)(i), in the event the Company shall hereafter issue or sell any Common Stock, any securities convertible into Common Stock or any rights, options or warrants to purchase Common Stock or securities convertible into Common Stock, in each case for a price per share or entitling the holders thereof to purchase Common Stock at a price per share (the "ISSUE PRICE"), (determined by dividing (i) the Total Consideration by (ii) the number of additional Page 83 of 99 Pages shares of Common Stock issuable upon exercise or conversion of such securities) which is less than the then current Per Share Exercise Price in effect on the record date of such issuance, the Per Share Exercise Price shall be adjusted to equal the Issue Price. (d) In the event of any capital reorganization or reclassification, or any consolidation or merger to which the Company is a party other than a merger or consolidation in which the Company is the continuing corporation, or in case of any sale or conveyance to another entity of the property of the Company as an entirety or substantially as an entirety, or in the case of any statutory exchange of securities with another corporation (including any exchange effected in connection with a merger of a third corporation into the Company), the Holder of this Warrant shall have the right thereafter to receive on the exercise of this Warrant the kind and amount of securities, cash or other property which the Holder would have owned or have been entitled to receive immediately after such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance had this Warrant been exercised immediately prior to the effective date of such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance and in any such case, if necessary, appropriate adjustment shall be made in the application of the provisions set forth in this Section 3 with respect to the rights and interests thereafter of the Holder of this Warrant to the end that the provisions set forth in this Section 3 shall thereafter correspondingly be made applicable, as nearly as may reasonably be, in relation to any shares of stock or other securities or property thereafter deliverable on the exercise of this Warrant. The above provisions of this subsection 3(e) shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, statutory exchanges, sales or conveyances. The issuer of any shares of stock or other securities or property thereafter deliverable on the exercise of this Warrant shall be responsible for all of the agreements and obligations of the Company hereunder. Notice of any such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance and of said provisions so proposed to be made, shall be mailed to the Holders of the Warrants not less than 30 days prior to such event. A sale of all or substantially all of the assets of the Company for a consideration consisting primarily of securities shall be deemed a consolidation or merger for the foregoing purposes. (e) In case any event shall occur as to which the other provisions of this Section 3 are not strictly applicable but as to which the failure to make any adjustment would not fairly protect the purchase rights represented by this Warrant in accordance with the essential intent and principles hereof then, in each such case, the Holders of Warrants representing the right to purchase a majority of the Warrant Shares subject to all outstanding Warrants may appoint a firm of independent public accountants of recognized national standing reasonably acceptable to the Company, which shall give their opinion as to the adjustment, if any, on a basis consistent with the essential intent and principles established herein, necessary to preserve the purchase rights represented by the Warrants. Upon receipt of such opinion, the Company will promptly mail a copy thereof to the Holder of this Warrant and shall make the adjustments described therein. The fees and expenses of such independent public accountants shall be borne by the Company. (f) Whenever the Per Share Exercise Price payable upon exercise of each Warrant is adjusted pursuant to this Section 3, the number of shares of Common Stock underlying a Warrant shall simultaneously be adjusted to equal the number obtained by dividing the Aggregate Exercise Price by the adjusted Per Share Exercise Price. (g) No adjustment in the Per Share Exercise Price shall be required unless such adjustment would require an increase or decrease of at least $0.01 per share of Common Stock; provided, however, that any adjustments which by reason of this subsection 3(g) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 3 shall be made to the nearest cent or to the nearest 1/100th of a share, as the case may be. Anything in this Section 3 to the contrary notwithstanding, the Company shall be entitled to make such reductions in the Per Share Exercise Price, in addition to those required by this Section 3, as it in its discretion shall deem to be advisable in order that any stock dividend, subdivision of shares or distribution of rights to purchase stock or securities convertible or exchangeable for stock hereafter made by the Company to its stockholders shall not be taxable. Page 84 of 99 Pages (h) Whenever the Per Share Exercise Price is adjusted as provided in this Section 3 and upon any modification of the rights of a Holder of Warrants in accordance with this Section 3, the Company shall promptly obtain, at its expense, a certificate of a firm of independent public accountants of recognized standing selected by the Board of Directors (who may be the regular auditors of the Company) setting forth the Per Share Exercise Price and the number of Warrant Shares after such adjustment or the effect of such modification, a brief statement of the facts requiring such adjustment or modification and the manner of computing the same and cause copies of such certificate to be mailed to the Holders of the Warrants. (i) If the Board of Directors of the Company shall declare any dividend or other distribution with respect to the Common Stock, the Company shall mail notice thereof to the Holders of the Warrants not less than 30 days prior to the record date fixed for determining stockholders entitled to participate in such dividend or other distribution. (j) If, as a result of an adjustment made pursuant to this Section 3, the Holder of any Warrant thereafter surrendered for exercise shall become entitled to receive shares of two or more classes of capital stock or shares of Common Stock and other capital stock of the Company, the Board of Directors (whose determination shall be conclusive and shall be described in a written notice to the Holder of any Warrant promptly after such adjustment) shall determine the allocation of the adjusted Per Share Exercise Price between or among shares or such classes of capital stock or shares of Common Stock and other capital stock. (k) For the purpose of any computation under Section 3 above, the then Current Market Price per share (the "CURRENT MARKET PRICE") shall be deemed to be the last sale price of the Common Stock on the trading day prior to such date or, in case no such reported sales take place on such day, the average of the last reported bid and asked prices of the Common Stock on such day, in either case on the principal national securities exchange on which the Common Stock is admitted to trading or listed, or if not listed or admitted to trading on any such exchange, the representative closing bid price of the Common Stock as reported by the National Association of Securities Dealers, Inc. Automated Quotations System ("NASDAQ"), or other similar organization if NASDAQ is no longer reporting such information, or, if the Common Stock is not reported on NASDAQ, the high per share bid price for the Common Stock in the over-the-counter market as reported by the National Quotation Bureau or similar organization, or if not so available, the fair market value of the Common Stock as determined by agreement between the Company's Board of Directors, on the one part, and the Holders of Warrants representing the right to purchase a majority of the Warrant Shares subject to all outstanding Warrants, on the second part. If the Board of Directors and such Holders fail to agree on the Current Market Price within 60 days of the date of the action giving rise to any adjustment pursuant to this Section 3, such Holders shall be entitled to appoint a firm of independent public accountants or appraisers of recognized national standing reasonably acceptable to the Company, which shall give their opinion as to such Current Market Price on a basis consistent with the essential intent and principles established herein. Upon receipt of such opinion, the Company will promptly mail a copy thereof to the Holder of this Warrant and shall make the adjustments described therein. The fees and expenses of such independent public accountants or appraisers shall be borne by the Company. 4. REGISTRATION UNDER SECURITIES ACT OF 1933. The resale of the Warrant Shares shall be registered on the Shelf Registration Statement (as defined in Article 8 of the Note and Warrant Purchase Agreement (the "Purchase Agreement") dated as of January 28, 1997, by and among the Company, The Aries Fund, a Cayman Island Trust, and The Aries Domestic Fund, L.P., a Delaware limited partnership) and certain purchasers and the Holder of this Warrant shall have the registration rights as provided in Article 8 of the Purchase Agreement.

Other than the exercise price, the New Warrants shall have the same terms as the Class A Warrants. To the extent that there is no Required Shareholder Approval necessary the foregoing clause (b) shall be ignored. Notwithstanding the foregoing, the New Warrants' exercise price shall be adjusted at the time of the Final Closing Date (as that term is defined in the Letter between Genta and Paramount Capital Inc., dated January 28, 1997) if the exercise price of the Offering Warrants (as defined below) is less than the exercise price of the New Warrants. In such event the New Warrants exercise price shall be reduced to equal 50% of the then current exercise price of the Offering Warrants (as hereafter defined).
