Shelf Registration Rights Agreement

This Shelf Registration Rights Agreement (this "Agreement") is made and entered into as of December 12, 2001, by and among Alpharma Operating Corporation, a Delaware corporation (the "Company"), Alpharma Inc., ("Alpharma"), a Delaware corporation, and the other Guarantors named in Schedule A (together with Alpharma, the "Guarantors"), and Banc of America Bridge LLC and CIBC Inc. (each a "Purchaser" and, collectively, the "Purchasers"), each of whom has agreed to purchase the Company's 12% Senior Subordinated Notes due 2009 (the "Initial Notes") pursuant to the Note Purchase Agreement (as defined below).

This Agreement is made pursuant to the Note Purchase Agreement, dated as of December 12, 2001 (the "Note Purchase Agreement"), by and among the Company, the Guarantors and the Purchasers (i) for the benefit of each Purchaser and (ii) for the benefit of the holders from time to time of the Notes (including each Purchaser).  In order to induce the Purchasers to purchase the Initial Notes, the Company has agreed to provide the registration rights set forth in this Agreement.  Capitalized terms not defined herein are used as defined in the Note Purchase Agreement.

The parties hereby agree as follows:

1. Definitions
2. Securities Subject to This Agreement
3. Transfer Restricted Securities.  The securities entitled to the benefits of this Agreement are the Transfer Restricted Securities.
4. Holders of Transfer Restricted Securities.  A Person is deemed to be a holder of Transfer Restricted Securities (each, a "Holder") whenever such Person owns Transfer Restricted Securities.





(x)  cause to be filed a shelf registration statement pursuant to Rule 415 under the Securities Act, (the "Shelf Registration Statement") as soon as practicable after the Closing Date, but in no event after the later of 15 days after the Acquisition closes and 90 days from the Issue Date (such date being the "Shelf Filing Deadline"), which Shelf Registration Statement shall provide for resales of all Exchange Notes to be issued in exchange for Transfer Restricted Securities the Holders of which shall have provided the information required pursuant to Section 3(b) hereof; and

(y)  use their best efforts to cause such Shelf Registration Statement to be declared effective by the Commission on or before the 90th day after the Shelf Filing Deadline.

The Company and the Guarantors shall use their best efforts to keep such Shelf Registration Statement continuously effective, supplemented and amended as required by the provisions of Sections 5(a) and (b) hereof to the extent necessary to ensure that it is available for resales of Exchange Notes by the Holders of Transfer Restricted Securities, and to ensure that it conforms with the requirements of this Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced from time to time, for a period of at least two years following the effective date of such Shelf Registration Statement (or shorter period that will terminate when all the Exchange Notes covered by such Shelf Registration Statement have been sold pursuant to such Shelf Registration Statement).



(ii)  No Holder of Transfer Restricted Securities may resell any of its Transfer Restricted Securities under the Shelf Registration Statement pursuant to this Agreement unless and until such Holder surrenders to the Company such Transfer Restricted Securities that it desires to sell in exchange for any equal principal amount of Exchange Notes.

If (i) the Shelf Registration Statement required by this Agreement is not filed with the Commission on or prior to the date specified for such filing in this Agreement, (ii) the Shelf Registration Statement has not been declared effective by the Commission on or prior to the date specified for such effectiveness in Section 3 of this Agreement (the "Effectiveness Target Date"), or (iii) the Shelf Registration Statement is filed and declared effective but shall thereafter cease to be effective or fail to be usable in connection with resales of Exchange Notes without being succeeded immediately by a post-effective amendment to such Shelf Registration Statement that cures such failure and that is itself immediately declared effective (each such event referred to in clauses (i) through (iii), a "Registration Default"), the Company and the Guarantors hereby jointly and severally agree to pay to each Holder of Transfer Restricted Securities affected thereby liquidated damages in an amount equal to one half of one percent (0.50%) per annum on the principal amounts of the Transfer Restricted Securities held by such Holder during the 90-day period immediately following the occurrence of any Registration Default and shall increase by an additional one half of one percent (0.50%) per annum on the principal amounts of such Transfer Restricted Securities at the end of each subsequent 90-day period, but in no event shall such increase exceed 1.50% per annum.  Following the cure of all Registration Defaults relating to any particular Transfer Restricted Securities, the liquidated damages payable with respect to the Transfer Restricted Securities as a result of the provisions of this paragraph shall cease.

All obligations of the Company and the Guarantors set forth in the preceding paragraph that are outstanding with respect to any Transfer Restricted Security at the time such security ceases to be a Transfer Restricted Security shall survive until such time as all such obligations with respect to such Note shall have been satisfied in full.







1. use their best efforts to keep the Shelf Registration Statement continuously effective and provide all requisite financial statements (including, if required by the Securities Act or any regulation thereunder, financial statements of the Guarantors) for the period specified in Section 3 of this Agreement, as applicable; upon the occurrence of any event that would cause such Shelf Registration Statement or the Prospectus contained therein (A) to contain a material misstatement or omission or (B) not to be effective and usable for resale of the Exchange Notes during the period required by this Agreement, the Company and the Guarantors shall file promptly an appropriate amendment to such Shelf Registration Statement, in the case of clause (A), correcting any such misstatement or omission, and, in the case of either clause (A) or (B), use their best efforts to cause such amendment to be declared effective and such Shelf Registration Statement and the related Prospectus to become usable for their intended purpose(s) as soon as practicable thereafter;
2. prepare and file with the Commission such amendments and post-effective amendments to the Shelf Registration Statement as may be necessary to keep the Shelf Registration Statement effective for the applicable period set forth in Section 3 hereof, or such shorter period as will terminate when all the Exchange Notes covered by such Shelf Registration Statement have been sold; cause the Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities Act, and to comply fully with the applicable provisions of Rules 424 and 430A under the Securities Act in a timely manner; and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Shelf Registration Statement during the applicable period in accordance with the intended method or methods of distribution by the sellers thereof set forth in such Shelf Registration Statement or supplement to the Prospectus;
3. advise the underwriter(s), if any, and selling Holders promptly and, if requested by such Persons, confirm such advice in writing, (A) when the Prospectus or any Prospectus supplement or post-effective amendment has been filed, and, with respect to the Shelf Registration Statement or any post-effective amendment thereto, when the same has become effective, (B) of any request by the Commission for amendments to the Shelf Registration Statement or amendments or supplements to the Prospectus or for additional information relating thereto, (C) of the issuance by the Commission of any stop order suspending the effectiveness of the Shelf Registration Statement under the Securities Act or of the suspension by any state securities commission of the qualification of the Exchange Notes for offering or sale in any jurisdiction, or the initiation of any proceeding for any of the preceding purposes, (D) of the existence of any fact or the happening of any event that makes any statement of a material fact made in the Shelf Registration Statement, the Prospectus, any amendment or supplement thereto, or any document incorporated by reference therein untrue, or that requires the making of any additions to or changes in the Shelf Registration Statement or the Prospectus in order to make the statements therein not misleading.  If at any time the Commission shall issue any stop order suspending the effectiveness of the Shelf Registration Statement, or any state securities commission or other regulatory authority shall issue an order suspending the qualification or exemption from qualification of the Exchange Notes under state securities or Blue Sky laws, the Company and the Guarantors shall use their best efforts to obtain the withdrawal or lifting of such order at the earliest possible time;
4. furnish without charge to each of the Purchasers, each selling Holder named in the Shelf Registration Statement, and each of the underwriter(s), if any, before filing with the Commission, copies of the Shelf Registration Statement or any Prospectus included therein or any amendments or supplements to any such Shelf Registration Statement or Prospectus (including all documents incorporated by reference after the initial filing of such Shelf Registration Statement), which documents will be subject to the review of such Holders and underwriter(s) in connection with such sale, if any, for a period of at least five business days, and the Company will not file any such Shelf Registration Statement or Prospectus or any amendment or supplement to any such Shelf Registration Statement or Prospectus (including all such documents incorporated by reference) to which a Holder of Exchange Notes covered by such Shelf Registration Statement or the underwriter(s), if any, shall reasonably object in writing within five business days after the receipt thereof (such objection to be deemed timely made upon confirmation of telecopy transmission within such period).  The objection of an or underwriter, if any, shall be deemed to be reasonable if such Shelf Registration Statement, amendment, Prospectus or supplement, as applicable, as proposed to be filed, contains a material misstatement or omission;
5. promptly prior to the filing of any document that is to be incorporated by reference into the Shelf Registration Statement or Prospectus, provide copies of such document to the Purchasers, each selling Holder named in the Shelf Registration Statement, and to the underwriter(s), if any, make available the representatives of the Company and the Guarantors for discussion of such document and other customary due diligence matters, and include such information in such document prior to the filing thereof as such selling Holders or underwriter(s), if any, reasonably may request;
6. make available at reasonable times for inspection by the Purchasers, any managing underwriter participating in any disposition pursuant to such Shelf Registration Statement and any attorney or accountant retained by such Purchasers or any of the underwriter(s), all financial and other records, pertinent corporate documents and properties of the Company and the Guarantors and cause the Company's and the Guarantors' officers, directors and employees to supply all information reasonably requested by any such Holder, underwriter, attorney or accountant in connection with such Shelf Registration Statement subsequent to the filing thereof and prior to its effectiveness;
7. if requested by any selling Holders or the underwriter(s), if any, promptly incorporate in the Shelf Registration Statement or Prospectus, pursuant to a supplement or post-effective amendment if necessary, such information as such selling Holders and underwriter(s), if any, may reasonably request to have included therein, including, without limitation, information relating to the "Plan of Distribution" of the Exchange Notes, information with respect to the principal amount of Exchange Notes being sold to such underwriter(s), the purchase price being paid therefor and any other terms of the offering of the Exchange Notes to be sold in such offering; and make all required filings of such Prospectus supplement or post-effective amendment as soon as practicable after the Company is notified of the matters to be incorporated in such Prospectus supplement or post-effective amendment;
8. cause the Exchange Notes covered by the Shelf Registration Statement to be rated with the appropriate rating agencies, if so requested by the Holders of a majority in aggregate principal amount of Notes covered thereby or the underwriter(s), if any;

10. deliver to each selling Holder and each of the underwriter(s), if any, without charge, as many copies of the Prospectus (including each preliminary prospectus) and any amendment or supplement thereto as such Persons reasonably may request; the Company and the Guarantors hereby consent to the use of the Prospectus and any amendment or supplement thereto by each of the selling Holders and each of the underwriter(s), if any, in connection with the offering and the sale of the Exchange Notes covered by the Prospectus or any amendment or supplement thereto;
11. enter into, and cause the Guarantors to enter into, such agreements (including an underwriting agreement), and make, and cause the Guarantors to make, such representations and warranties, and take all such other actions in connection therewith in order to expedite or facilitate the disposition of the Exchange Notes pursuant to the Shelf Registration Statement contemplated by this Agreement, all to such extent as may be reasonably requested by any Purchaser or by any Holder of Exchange Notes or underwriter in connection with any sale or resale pursuant to the Shelf Registration Statement contemplated by this Agreement; and whether or not an underwriting agreement is entered into and whether or not the registration is an Underwritten Registration, the Company and the Guarantors shall:
12. furnish to each Purchaser, each selling Holder and each underwriter, if any, in such substance and scope as they may request and as are customarily made by issuers to underwriters in primary underwritten offerings, upon the date of the effectiveness of the Shelf Registration Statement:
13. a certificate, dated the date of effectiveness of the Shelf Registration Statement signed by (y) the President or any Vice President and (z) a principal financial or accounting officer of each of the Company and the Guarantors, to the effect that:

1. the representations and warranties of the Company, Alpharma and the other Guarantors set forth in Section 2 of the Note Purchase Agreement are true and correct with the same force and effect as though expressly made on and as of the date of effectiveness of the Shelf Registration Statement (other than (i) representations and warranties that by their terms refer to a certain date, which shall be true and correct only as of such date, and (ii) the representations and warranties contained in paragraphs (a), (c), (h) and (l) of such Section 2);
2. except as otherwise disclosed in the Shelf Registration Statement, subsequent to the respective dates as of which information is given in the Shelf Registration Statement Alpharma and its subsidiaries, considered as one entity, have not incurred any material liability or obligation, indirect, direct or contingent, not in the ordinary course of business nor entered into any material transaction or agreement not in the ordinary course of business; and
3. the Company and the Guarantors have complied with all the agreements and satisfied all the conditions on their part to be performed or satisfied under this Agreement at or prior to the Closing Date.

1. opinions, dated the date of effectiveness of the Shelf Registration Statement of Kirkland & Ellis, counsel for the Company and the Guarantors, and of Robert F. Wrobel, Senior Vice President and Chief Legal Officer of Alpharma, in the form of Exhibits A-1 and A-2 to the Note Purchase Agreement and such other matters as such parties may reasonably request, and in any event including, in each case, a statement to the effect that such counsel has participated in conferences with officers and other representatives of the Company and the Guarantors, representatives of the independent public accountants for the Company and the Guarantors, the Purchasers' representatives and the Purchasers' counsel in connection with the preparation of the Shelf Registration Statement and the related Prospectus and have considered the matters required to be stated therein and the statements contained therein, although such counsel has not independently verified the accuracy, completeness or fairness of such statements; and that such counsel advises that, on the basis of the foregoing (relying as to materiality to a large extent upon facts provided to such counsel by officers and other representatives of the Company and the Guarantors and without independent check or verification), no facts came to such counsel's attention that caused such counsel to believe that the Shelf Registration Statement, at the time such Shelf Registration Statement or any post-effective amendment thereto became effective, contains an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.  Without limiting the foregoing, such counsel may state further that such counsel assumes no responsibility for, and has not independently verified, the accuracy, completeness or fairness of the financial statements, notes and schedules and other financial data included in the Shelf Registration Statement contemplated by this Agreement or the related Prospectus; and
2. a customary comfort letter, dated as of the date of effectiveness of the Shelf Registration Statement from the Company's independent accountants, in the customary form and covering matters of the type customarily covered in comfort letters by underwriters in connection with primary underwritten offerings;

1. set forth in full or incorporate by reference in the underwriting agreement, if any, the indemnification provisions and procedures of Section 8 hereof with respect to all parties to be indemnified pursuant to said Section; and
2. deliver such other documents and certificates as may be reasonably requested by such parties to evidence compliance with clause (A) above and with any customary conditions contained in the underwriting agreement or other agreement entered into by the Company or the Guarantors pursuant to this clause (xi), if any.

If at any time the representations and warranties of the Company and the Guarantors contemplated in clause (A)(1)(aa) above cease to be true and correct, the Company or the Guarantors shall so advise the Purchasers and the underwriter(s), if any, and each selling Holder promptly and, if requested by such Persons, shall confirm such advice in writing;

1. prior to any public offering of Exchange Notes in respect of Transfer Restricted Securities, cooperate with, and cause the Guarantors to cooperate with, the selling Holders, the underwriter(s), if any, and their respective counsel in connection with the registration and qualification of such Exchange Notes under the securities or Blue Sky laws of such jurisdictions as the selling Holders or underwriter(s) may request and do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Exchange Notes covered by the Shelf Registration Statement; provided, however, that neither the Company nor the Guarantors shall be required to register or qualify as a foreign corporation where it is not then so qualified or to take any action that would subject it to the service of process in suits or to taxation, other than as to matters and transactions relating to the Shelf Registration Statement, in any jurisdiction where it is not then so subject;

4. if any fact or event contemplated by clause (b)(iii)(D) above shall exist or have occurred, prepare a supplement or post-effective amendment to the Shelf Registration Statement or related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of Exchange Notes, the Prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading;
5. obtain CUSIP numbers for all Restricted Securities or Exchange Notes not later than the effective date of the Shelf Registration Statement and provide the Purchasers under the Note Purchase Agreement with printed certificates for the Exchange Notes which are in a form eligible for deposit with the Depositary Trust Company;
6. cooperate and assist in any filings required to be made with the NASD and in the performance of any due diligence investigation by any underwriter (including any "qualified independent underwriter") that is required to be retained in accordance with the rules and regulations of the NASD, and use its reasonable best efforts to cause the Shelf Registration Statement to become effective and approved by such governmental agencies or authorities as may be necessary to enable the Holders of Transfer Restricted Securities to consummate the disposition of Exchange Notes in respect of such Transfer Restricted Securities;
7. otherwise use its best efforts to comply with all applicable rules and regulations of the Commission, and make generally available to its security holders, as soon as practicable, a consolidated earnings statement meeting the requirements of Rule 158 (which need not be audited) for the twelve-month period (A) commencing at the end of any fiscal quarter in which Exchange Notes are sold to underwriters in a firm or best efforts Underwritten Offering or (B) if not sold to underwriters in such an offering, beginning with the first month of the Company's first fiscal quarter commencing after the effective date of the Shelf Registration Statement;

9. provide promptly to each Holder upon request each document filed with the Commission pursuant to the requirements of Section 13 and Section 15 of the Exchange Act; and

Each Holder agrees by acquisition of a Transfer Restricted Security that, upon receipt of any notice from the Company of the existence of any fact of the kind described in Section 5(b)(iii)(D) hereof, such Holder will forthwith discontinue disposition of Exchange Notes in respect of Transfer Restricted Securities pursuant to the Shelf Registration Statement until such Holder's receipt of the copies of the supplemented or amended Prospectus contemplated by Section 5(b)(xvi) hereof, or until it is advised in writing (the "Advice") by the Company that the use of the Prospectus may be resumed, and has received copies of any additional or supplemental filings that are incorporated by reference in the Prospectus.  If so directed by the Company, each Holder will deliver to the Company (at the Company's expense) all copies, other than permanent file copies then in such Holder's possession, of the Prospectus covering such Exchange Notes that was current at the time of receipt of such notice.  In the event the Company shall give any such notice, the time period regarding the effectiveness of the Shelf Registration Statement set forth in Section 3 hereof shall be extended by the number of days during the period from and including the date of the giving of such notice pursuant to Section 5(b)(iii)(D) hereof to and including the date when each selling Holder shall have received the copies of the supplemented or amended Prospectus contemplated by Section 5(b)(xvi) hereof or shall have received the Advice; however, no such extension shall be taken into account in determining whether Liquidated Damages are due pursuant to Section 4 hereof or the amount of such Liquidated Damages, it being agreed that the Company's option to suspend use of the Shelf Registration Statement pursuant to this paragraph shall be treated as a Registration Default for purposes of Section 4.

1. Registration Expenses
2. All expenses incident to the Company's or the Guarantors' performance of or compliance with this Agreement will be borne by the Company or such Guarantor, regardless of whether the Shelf Registration Statement becomes effective, including without limitation: (i) all registration and filing fees and expenses (including filings made by any Purchaser or Holder with the NASD (and, if applicable, the fees and expenses of any "qualified independent underwriter" and its counsel that may be required by the rules and regulations of the NASD)); (ii) all fees and expenses of compliance with federal securities and state Blue Sky or securities laws; (iii) all expenses of printing, messenger and delivery services and telephone; (iv) all fees and disbursements of counsel for the Company, the Guarantors and, subject to Section 6(b) below, the Holders of Transfer Restricted Securities; (v) all application and filing fees in connection with listing the Notes on a national securities exchange or automated quotation system pursuant to the requirements thereof; and (vi) all fees and disbursements of independent certified public accountants of the Company and the Guarantors (including the expenses of any special audit and comfort letters required by or incident to such performance).
3. In connection with the Shelf Registration Statement, the Company and the Guarantors will reimburse the Purchasers and the Holders of Transfer Restricted Securities being registered pursuant to the Shelf Registration Statement for the reasonable fees and disbursements of not more than one counsel in an amount not to exceed $10,000, who shall be Shearman & Sterling or such other counsel as may be chosen by the Holders of a majority in principal amount of the Transfer Restricted Securities.











The Company, the Guarantors and each Holder of Transfer Restricted Securities agree that it would not be just and equitable if contribution pursuant to this Section 7(c) were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph.  The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or expenses referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim.  Notwithstanding the provisions of this Section 7, none of the Holders (and its related Indemnified Holders) shall be required to contribute, in the aggregate, any amount in excess of the amount by which the total amount of the commitment fee received by such Holder under the Fee Letter with respect to the Initial Notes exceeds the amount of any damages which such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  The Holders' obligations to contribute pursuant to this Section 7(c) are several in proportion to the respective principal amount of Initial Notes held by each of the Holders hereunder and not joint.

The Company and the Guarantors each hereby agrees with each Holder, for so long as any Transfer Restricted Securities remain outstanding, to make available to any Holder or beneficial owner of Transfer Restricted Securities in connection with any sale thereof and any prospective purchaser of such Transfer Restricted Securities from such Holder or beneficial owner, the information required by Rule 144A(d)(4) under the Securities Act in order to permit resales of such Transfer Restricted Securities pursuant to Rule 144A.

No Holder may participate in any Underwritten Registration hereunder unless such Holder (a) agrees to sell any Exchange Notes in respect of such Holder's Transfer Restricted Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes all reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents required under the terms of such underwriting arrangements.

The Holders of Transfer Restricted Securities covered by the Shelf Registration Statement who desire to do so may sell any Exchange Notes in respect of such Transfer Restricted Securities in an Underwritten Offering.  In any such Underwritten Offering, the investment banker or investment bankers and manager or managers that will administer the offering will be selected by the Holders of a majority in aggregate principal amount of the Transfer Restricted Securities included in such offering; provided, that such investment bankers and managers must be reasonably satisfactory to the Company.
