For purposes of this Section 6.3(c), a second (or subsequent) "indication" is defined as an addition to the indication section of the package insert for the Product only after a clinical program separate and distinct from the first clinical program is undertaken. Any such addition to the indication section shall represent a distinct disease category from the previously approved indication (i.e., additions to treat subpopulations within the previously approved indication or new or different treatment regimens for the previously approved indication do not apply). 14. (d) MILESTONE PAYMENTS. For purposes of clarification, (i) if any of the milestones set forth above in Sections 6.3(b)(i), 6.3(b)(ii) or 6.3(b)(iii) is achieved prior to or in the absence of the achievement of a preceding milestone, then, effective upon achievement of any of such milestones, any previously unpaid milestone shall also become due and payable and (ii) each milestone is payable pursuant to this Section 6.3 on an Amgen Gene Target-by-Amgen Gene Target basis only, and once one milestone has been paid with respect to a particular Amgen Gene Target no additional such milestone shall be paid with respect to such Amgen Gene Target, regardless of the number of Collaboration ASO Compounds, Amgen ASO Compounds and/or Products relative to each Amgen Gene Target which subsequently achieves such milestone event. 6.4 ROYALTIES. (a) ROYALTIES PAYABLE BY AMGEN. During the Royalty Term of each Product, Amgen shall pay to Isis, on a country-by-country basis, incremental royalties on total annual worldwide Net Sales of each such Product by Amgen, its Affiliates and its Sublicensees at the following rates: (i) [***] of that portion of total annual Net Sales of each such Product that is less than [***]; (ii) [***] of that portion of total annual Net Sales of each such Product that is greater than or equal to [***] and less than [***]; and (iii) [***] of that portion of total annual Net Sales of each such Product that is greater than or equal to [***]. (b) ROYALTY TERM. Royalties for sales of any Product shall be paid for a period equal to the Royalty Term for such Product. (c) [***] LICENSES. Amgen acknowledges that Isis may be obligated to pay royalties under the [***] License and the [***] License with respect to Net Sales of Products and agrees that, in addition to the royalties set forth in Section 6.4(a) above but subject to Section 6.4(e) below, Amgen shall pay to Isis a total of [***] of Net Sales of Products by Amgen, its Affiliates and its Sublicensees, which represents [***] of the total combined royalties payable by Isis under the [***] License and the [***] License with respect to Net Sales of Products by Amgen, its Affiliates and its Sublicensees. Upon the expiration or termination, on a country-by-country basis, of the obligation by Isis to pay royalties (or equivalent payments) to [***] under the [***] License or [***] under the [***] License, Amgen shall have the right to decrease the amount of its quarterly payment under Section 8.1 to Isis by [***] of the amount Amgen would have otherwise paid to Isis for such license in such country. After the expiration of the Royalty Term, Amgen agrees to pay [***] of the total combined royalties payable by Isis under the [***] License and/or the [***] License with respect to Net Sales of each Product for so long as such royalties are due and payable under the [***] License and/or the [***] License. Isis acknowledges and agrees that Isis is solely responsible for any and all obligations that may have accrued or may accrue in the future with respect to the [***] License and the [***] License; PROVIDED, HOWEVER, that Amgen shall be obligated to pay Isis the applicable amount under this 15. Section 6.4(c) with respect to any sale of a Product that would obligate Isis to make a royalty payment to [***] under the [***] License or to [***] under the [***] License. (d) THIRD PARTY LICENSES. If Amgen reasonably determines in its sole discretion, authority and right that one or more licenses (other than the [***] License and the [***] License) to access the intellectual property rights of a Third Party or Parties are required for Amgen, its Affiliates and/or its Sublicensees to research, develop, make, have made, use, import, offer to sell and/or sell, export or otherwise exploit, or transfer physical possession of or title in Collaboration ASO Compounds and/or Amgen ASO Compounds ("THIRD PARTY LICENSE(S)"), then: [***] of any compensation (including, without limitation, up-front payments, milestones and royalties) actually paid by Amgen, its Affiliates and Sublicensees with respect to the sale of any Product containing such Collaboration ASO Compound and/or Amgen ASO Compound under any such Third Party License(s) entered into by Amgen, its Affiliates or Sublicensees shall be creditable against the royalty payments to be paid to Isis by Amgen with respect to the sale of such Product; PROVIDED HOWEVER, that, on a Product-by-Product basis, Isis' royalty rate due under Section 6.4(a) in any given year will not be reduced to less than [***] of Net Sales of such Product as a consequence of any compensation (including, without limitation, up-front payments, milestones and royalties) actually paid by Amgen under any Third Party License(s) being creditable against the royalty payments to be paid to Isis by Amgen; FURTHER PROVIDED HOWEVER, that unused credits in any period may be carried forward against royalties due in future periods. (e) ELIMINATION OR REDUCTION OF THIRD PARTY ROYALTIES. Isis shall notify Amgen if Isis eliminates or reduces the royalty payments required under the [***] License or the [***] License that may be required in order for Amgen, its Affiliates and/or Sublicensees to develop, make, have made, use, import, offer to sell and/or sell or otherwise export, or transfer physical possession of or title in any Collaboration ASO Compound, Amgen ASO Compound and/or Product. Thereafter, Amgen shall have the option, exercisable upon written notice to Isis, to reduce the amount of royalties payable to Isis with respect to the [***] License and the [***] License pursuant to Section 6.4(c) for any Product by an amount that is equal to the portion of the pass-through royalty payments eliminated or reduced by Isis by paying to Isis an amount equal to [***] of the dollar amount paid by Isis to such Third Party to eliminate or reduce such pass-through royalty. In the event that non-monetary consideration is exchanged between Isis and the Third Party to eliminate or reduce such pass-through royalties, the parties will negotiate in good faith an adequate payment by Amgen to Isis for elimination or reduction of such pass-through royalty to Amgen. If the parties fail to determine an acceptable amount for such a payment by Amgen, or if Amgen does not exercise its option under this Section 6.4(e), then the royalty rate determined in accordance with Sections 6.4(a), (c) and (d) will remain in full force and effect as though Isis had not eliminated or reduced such pass-through royalty with respect to Isis' agreement with such Third Party. (f) INFLATION. The increments of annual Net Sales tiers set forth in Section 6.4(a)(i)-(iii) and the cumulative Net Sales milestone set forth in Section 6.3(c) shall be adjusted upward on a Calendar Year basis commencing January 1, 2003 (and on January 1 of each year thereafter during the term of this Agreement) by an amount equal to the percentage change, if any, in the Consumer Price Index for the preceding year. 16.

The parties will negotiate a license in good faith for use of such technology in connection with the license granted to Amgen in Section 5.1(a)(iii) above, on terms and conditions no less favorable than those made available by Isis to Third Party collaborators of Isis in similar transactions, including reasonable compensation to Isis. (h) CUMULATIVE ROYALTIES. The obligation under Article 6 to pay royalties on the Net Sales of a Product shall be imposed only once with respect to the same unit of said Product e.g., regardless of the number of claims within Isis Patent Rights which would, but for this Agreement, be infringed by the making, having made, using, selling, leasing, offering to sell or lease, importing, exporting or otherwise exploiting, or transferring physical possession of or title in, said Product in the Field anywhere in the world. (i) PAID-UP LICENSE. Upon the expiration of Amgen's obligation under this Section 6.4 to pay royalties on Net Sales of a Product in a country, Amgen shall have a fully paid-up, non-exclusive license, with the right to sublicense, to make, have made, use, sell, lease, offer to sell or lease, import, export or otherwise exploit, transfer physical possession of or otherwise transfer title in such Product in the Field in that country. (j) NO OTHER COMPENSATION. Other than as explicitly set forth (and as applicable) in this Article 6, and in Sections 4.6 and 13.1(a), Amgen shall not be obligated to pay any additional fees, milestone payments, royalties or any additional payments to Isis under this Agreement.

For purposes of this Section 6.4(k), the determination of Net Sales of Products for purposes of calculating the royalties payable by Amgen to Isis under Section 6.4(a) shall not include sales of products (other than Products of Sublicensees) by such Third Party receiving such sublicense or covenant not to sue. ARTICLE 7 COMPETITION 7.1 COMPETITION. In the event that one or more Competitive ASO Compounds are commercially available in the same country of sale as a Product (hereinafter referred to as 17. "Competition"), the applicable royalty rates due under Article 6 above shall be reduced by [***], subject to Section 7.3 below. 7.2 COMPETITION CALCULATION. For the purpose of calculating incremental royalties on total annual worldwide Net Sales of said Product, Net Sales of such Product in a country where no Competition exists and Net Sales of such Product in a country where Competition exists shall be allocated among the Net Sales increments [***] on a country by country basis in accordance with the ratios between (i) each of (x) annual Net Sales of such Product in countries where no Competition exists, and (y) annual Net Sales of such Product in countries where Competition exists; and (ii) total annual Net Sales of such Product (i.e., the ratios of (i)(x)/(ii) and (i)(y)/(ii)). 7.3 [***] LICENSES. Notwithstanding Section 7.1 above, Amgen's obligation to pay royalties payable by Isis under the [***] License and the [***] License with respect to Net Sales of each Product in accordance with Section 6.4(c) above remains in effect and shall not be subject to reduction under Section 7.1. 7.4 EXAMPLE CALCULATION. An example royalty calculation is attached hereto as Exhibit E. The parties acknowledge and agree that the example does not contain all possible facts and circumstances that may apply at any given period and that the formulas used in such example may not be the only formulas that can be used to achieve the same result. ARTICLE 8 PAYMENT; RECORDS; AUDITS 8.1 PAYMENT; REPORTS. Beginning with the Calendar Quarter after the First Commercial Sale of the first Product until the expiration of Amgen's obligation to pay royalties, royalty payments and reports of the sale of Products for each Calendar Quarter will be calculated and delivered to Isis under this Agreement within sixty (60) days of the end of each such Calendar Quarter, unless otherwise specifically provided herein. Notwithstanding the above, Amgen will provide within twenty-five (25) days of the end of each such Calendar Quarter an estimate of royalties due for such Calendar Quarter, such estimate being subject to change between the time reported and the time royalties are paid for such Calendar Quarter. Each payment of royalties will be accompanied by a report of Net Sales of Products in sufficient detail to permit confirmation of the accuracy of the royalty payment made, including, without limitation and on a country-by-country basis, the number of Products sold, the gross sales and Net Sales of Products, the royalties payable (in U.S. dollars), the method used to calculate the royalty and the exchange rates used. Amgen will keep (and will cause its Affiliates and Sublicensees to keep) complete and accurate records pertaining to the development of Products and the sale or other disposition of Products in sufficient detail to permit Isis to confirm the accuracy of all payments due hereunder. 8.2 EXCHANGE RATE; MANNER AND PLACE OF PAYMENT. All payments hereunder will be payable in U.S. dollars. With respect to each Calendar Quarter, for countries other than the United States, whenever conversion of payments from any foreign currency will be required, such conversion will be made at the average rate of exchange during the Calendar Quarter to which such payments relate, as reported in BLOOMBERG PROFESSIONAL, a service of Bloomberg L.P. 18. during the royalty period of such Net Sales, or in the event BLOOMBERG PROFESSIONAL is not available then THE WALL STREET JOURNAL, for the currency of the country in which the sale is made. All payments owed under this Agreement will be made by wire transfer in immediately available funds to a bank and account designated in writing by Isis, unless otherwise specified in writing by Isis. If, for reasons beyond the control of Amgen, its Affiliates and/or Sublicensees, Amgen (or its Affiliate or Sublicensee) is unable to convert a foreign currency into United States Dollars in a country where neither Amgen nor its Affiliates or Sublicensees has operations, or is restricted by law, regulation or court order from remitting royalties from any country of sale in which neither Amgen nor its Affiliates or Sublicensees has operations, Amgen shall cause such payment to be made to Isis by deposit to the credit and account of Isis or its designated nominee in any commercial bank designated by Isis in the applicable country. Amgen will deliver to Isis proper evidence of such deposit. 8.3 LATE PAYMENTS. In the event that any payment, including up-front fee, royalty, milestone and research payment, due hereunder is not made when due, the payment will accrue interest from the due date at the rate of [***] per month, PROVIDED HOWEVER, that Isis will provide Amgen written notice of its alleged failure to make such a payment, and no such interest shall accrue if within [***] business days thereafter Amgen makes such payment; AND FURTHER PROVIDED HOWEVER, that in no event shall such rate exceed the maximum legal annual interest rate. The payment of such interest will not limit a party from exercising any other rights it may have as a consequence of the lateness of any payment. In the event that Amgen receives two such notices in a given calendar year, Isis will no longer be obligated to give Amgen written notice for the remainder of that calendar year. 8.4 INCOME TAX WITHHOLDING. If laws, rules or regulations require withholding of income taxes or other taxes imposed upon payments set forth in Article 6, Amgen will make such withholding payments as required and will subtract such withholding payments from the payments set forth in Article 6. Amgen will submit appropriate proof of payment of the withholding taxes to Isis within a reasonable period of time. 8.5 AUDITS. (a) Amgen will keep complete and accurate records pertaining to the development of Products and the sale or other disposition of Products in sufficient detail to permit Isis to confirm the accuracy of all payments due hereunder, and such records will be open to inspection for three (3) years following the end of the period to which they pertain. Not more than once per year, Isis will have the right to cause an independent, certified public accountant reasonably acceptable to Amgen to audit such records to confirm Net Sales and royalty and other payments for a period covering not more than the preceding three (3) years. (b) Such audits may be exercised during normal business hours upon reasonable prior written notice to Amgen (but in no event less than a 30-day prior written notice). Isis shall submit an audit plan, including audit scope, to Amgen for Amgen's approval, which shall not be unreasonably withheld, prior to audit implementation. (c) The independent certified public accountant(s) shall keep confidential any information obtained during such inspection and shall report to Isis only the amounts of Net 19. Sales and royalties due and payable, but may include, in the event such accountant shall be unable to verify the correctness of any such payment, information relating to why such payment is unverifiable. Amgen shall receive a copy of each such report concurrently with receipt by Isis. In the event that such payment is unverifiable, Amgen and Isis shall use good faith efforts to arrive at an equitable solution. Prompt adjustments will be made by the parties to reflect the results of such audit. Isis shall bear the full cost of such audit unless such audit discloses an underpayment of more than [***] from the amount of the Net Sales or royalties or other payments due under this Agreement. In such case, Amgen shall bear the full cost of such certified public accountant to perform such audit and will promptly remit to Isis the amount of any underpayment. Upon the expiration of three (3) years following the end of any Calendar Year, the calculation of royalties payable with respect to such year shall be binding and conclusive upon Isis, Amgen and its Affiliates and Sublicensees shall be released from any liability or accountability with respect to royalties for such year, and Amgen shall no longer be required to retain such records for such year. 8.6 CONFIDENTIALITY. Isis shall treat all financial information subject to review under Article 8, or under any related sublicense agreement, as Amgen's Confidential Information. Isis shall be responsible for this financial information and shall cause its accounting firm to be bound to obligations of confidentiality at least as restrictive as Isis' obligations of confidentiality in this Agreement. ARTICLE 9 INTELLECTUAL PROPERTY 9.1 OWNERSHIP OF INVENTIONS. Ownership of inventions shall be determined in accordance with the rules of inventorship under United States patent laws. Isis shall own all Isis Know-How, Collaboration Know-How and all Patent Rights claiming Isis Know-How or Collaboration Know-How. Amgen shall own all Amgen Know-How and all Patent Rights claiming Amgen Know-How. All Joint Know-How and Joint Patent Rights shall be owned jointly by Isis and Amgen. 9.2 PATENT PROSECUTION AND MAINTENANCE. (a) It is the intention of the parties to secure broad patent protection for inventions. Without limiting the generality of the foregoing, the parties will use reasonable efforts to file patent applications containing Collaboration ASO Compound or Amgen ASO Compound composition of matter claims and claims directed to the use of such Collaboration ASO Compounds or Amgen ASO Compounds separately from patent applications containing claims directed to Isis Standard Chemistry and Isis Standard Chemistry Manufacturing Process. (b) Isis shall be responsible for the preparation, filing, prosecution, maintenance and defense before all patent offices of all Isis Patent Rights, other than Isis ASO Compound Patent Rights, [***]. (c) Amgen shall be responsible for the preparation, filing, prosecution, maintenance and defense before all patent offices of Isis ASO Compound Patent Rights 20. exclusively licensed to Amgen pursuant to Section 5.1(a) [***]. Amgen shall have the sole right, but not the obligation, to prepare, file, prosecute, maintain and defend before all patent offices all Amgen Patent Rights [***]. (d) Amgen shall be responsible for the preparation, filing, prosecution, maintenance and defense before all patent offices of Joint Patent Rights using mutually acceptable outside counsel, and shall initially bear the costs, expenses and fees thereof, provided that Amgen shall be entitled to reimbursement by Isis of [***] of such documented costs, expenses and fees within thirty (30) days after presenting a bill to Isis. Amgen will consult with Isis as to the preparation, filing, prosecution, and maintenance of such Joint Patent Rights reasonably prior to any deadline or action with the U.S. Patent & Trademark Office or any foreign patent office, and will furnish to Isis copies of all relevant documents reasonably in advance of such consultation. (e) The responsible party will keep the other party informed of progress with regard to the preparation, filing, prosecution, maintenance and defense before all patent offices of Isis Patent Rights subject to Sections 9.2(b), 9.2(c) and 9.2(d) that contain a claim which would otherwise be infringed by the making, having made, using, selling, offering for sale or importing of a Collaboration ASO Compound, Amgen ASO Compound and/or Product being developed or commercialized by Amgen. Each party will consider in good faith the requests and suggestions of the other party with respect to strategies for filing and prosecuting such Patent Rights. In the event that (i) Isis under Section 9.2(b) elects not to prepare, file, prosecute, maintain or defend a patent application claiming an invention which would, but for the licenses granted herein, be infringed by the making, having made, using, selling, offering for sale or importing of a Collaboration ASO Compound, Amgen ASO Compound and/or Product being developed or commercialized by Amgen, or (ii) Amgen under Section 9.2(c) elects to discontinue prosecution, maintenance or defense of any Isis ASO Compound Patent Right claiming the manufacture, use, sale, offer for sale or import of a Product being developed or commercialized by Amgen, or (iii) either party under Section 9.2(d) elects to discontinue sharing expenses with respect to the preparation, filing, prosecution, maintenance and defense of any Joint Patent Rights, such party shall provide reasonable prior written notice to the other party of such intention to discontinue its efforts, and the other party (the "CONTINUING PARTY") shall have the right, at its expense, to prepare, file, prosecute, maintain and defend such Patent Right (the "DISCONTINUED PATENT"). The Continuing Party will own such Discontinued Patent and be solely responsible for all costs associated with the continuing activities described in the preceding sentence; PROVIDED, HOWEVER, that if Amgen is the Continuing Party, [***] of Amgen's reasonable documented costs associated with such continuing activities shall be creditable against the royalty payments to be paid to Isis by Amgen pursuant to Section 6.4(a), unless no such royalty payments are due thereunder with respect to the applicable Product in the applicable territory. Solely with respect to Discontinued Patents under the preceding clauses (i) and (ii) of this Section 9.2(e) (but, for the avoidance of doubt, not under the preceding clause (iii) of this Section 9.2(a)), the non-Continuing Party will have a non-exclusive, perpetual, irrevocable, fully-paid license to continue to practice such Discontinued Patent in the applicable territory where such Discontinued Patent is filed, including the right to sublicense solely in connection with the grant of a license to develop, make, have made, use, sell, offer for sale, have sold and import a product of such non-Continuing Party, except that if Isis is the non-Continuing Party, such license shall exclude the right to develop, make, have made, use, sell, offer for sale, have 21. sold and import products containing ASO Compounds that selectively modulate expression of an Amgen Gene Target. The non-Continuing Party shall execute such documents and perform such acts as may be reasonably necessary for the Continuing Party to prepare, file, prosecute, maintain or defend any such Discontinued Patent, including assigning ownership of such Discontinued Patent and the invention(s) claimed therein to the Continuing Party. (f) A decision by a party not to prepare, file, prosecute, maintain or defend any patent application or patent shall not affect any of its rights to practice certain Patent Rights under the licenses granted to the parties in Article 5 of this Agreement; provided however, in the event Isis is the non-Continuing Party, or if Amgen is the non-Continuing Party but Isis does not elect to proceed with preparing, filing, prosecuting, maintaining or defending any such Discontinued Patent, Amgen shall cease to have any obligation to pay royalties to Isis under this Agreement with respect to such Discontinued Patent in respect of Amgen's manufacture, use, sale, offer for sale or import of Products in such territory. 9.3 COOPERATION OF THE PARTIES. Each party agrees to cooperate fully (and to cause any employee, consultant or agent who worked on the Collaboration to cooperate) in the preparation, filing, prosecution and defense of any Patent Rights under this Agreement. Such cooperation includes, but is not limited to: (a) executing all papers and instruments, or requiring its employees or agents to execute such papers and instruments, so as to effectuate the ownership of inventions set forth in Section 8.1 and Patent Rights claiming such inventions, and to enable the other party to apply for and to prosecute patent applications in any country; and (b) promptly informing the other party of any matters coming to such party's attention that may affect the preparation, filing, prosecution or defense of any such patent applications. 9.4 INFRINGEMENT BY THIRD PARTIES. (a) Isis and Amgen will promptly notify the other in writing of any alleged or threatened infringement of any patent included in the Isis Patent Rights, Amgen Patent Rights or Joint Patent Rights of which they become aware that is likely to have a materially adverse effect on any Product being developed or commercialized by Amgen, its Affiliates or Sublicensees pursuant to a license granted under Section 5.1(a)(iii). (b) At its own expense and by counsel of its own choice, Amgen shall have the sole right, but not the obligation, to bring and control any action or proceeding, including, without limitation, the right to settle or compromise such proceedings, with respect to infringement of (i) any patent included in the Isis ASO Compound Patent Rights, (ii) any Joint Patent Rights claiming any Amgen Gene Target or any ASO Compound directed thereto, (iii) the Amgen Patent Rights and (iv) any right relating to the Collaboration Know-How, any Joint Know-How directed to an Amgen Gene Target or any ASO Compound directed thereto and the Amgen Know-How. Isis shall cooperate and, if Amgen finds it necessary or desirable, join Amgen as a party in such litigation, including the signing of any necessary legal papers, and shall provide Amgen with data or other information in support thereof, and shall use best efforts to 22. ensure the cooperation of any of its respective personnel as might reasonably be requested in any such matters. (c) Amgen shall have the first right, but not the obligation, to bring and control any action or proceeding with respect to infringement of any patent included in the Joint Patent Rights not claiming any Amgen Gene Target or any ASO Compound directed thereto and of any right relating to Joint Know-How not directed to any Amgen Gene Target or any ASO Compound directed thereto, at its own expense and by counsel of its own choice, and Isis shall have the right, at its own expense, to be represented in any such action by counsel of its own choice, and if Amgen fails to bring such an action or proceeding within (i) sixty (60) days following the notice of alleged infringement by or to Isis pursuant to Section 9.4(a) or (ii) ten (10) business days before the time limit, if any, set forth in the appropriate laws and regulations for the filing of such actions, whichever comes first, Isis shall have the right to bring and control any such action at its own expense and by counsel of its own choice, and Amgen shall have the right, at its own expense, to be represented in any such action by counsel of its own choice. The mutual consent of both parties is required before either party has the right to settle or compromise any proceedings with respect to infringement of any patent included in Joint Patent Rights other than Joint Patent Rights claiming any Amgen Gene Target or ASO Compounds directed thereto. (d) Isis shall have the sole right, but not the obligation, to bring and control any action or proceeding with respect to infringement of any patent included in the Isis Core Technology Patent Rights and Isis Manufacturing Patent Rights and of any right relating to Isis Know-How, at its own expense and by counsel of its own choice; PROVIDED HOWEVER, that with respect to infringement of any Isis Core Technology Patent Right or Isis Manufacturing Patent Right or of any right relating to Isis Know-How that is likely to have a materially adverse effect on any Product being developed or commercialized by Amgen, its Affiliates or Sublicensees pursuant to a license granted under Section 5.1(a)(iii), Amgen shall have the right, at its own expense, to be represented in any such action by counsel of its own choice, and if Isis fails to bring such an action or proceeding within (i) sixty (60) days following the notice of alleged infringement by or to Amgen pursuant to Section 9.4(a) or (ii) ten (10) business days before the time limit, if any, set forth in the appropriate laws and regulations for the filing of such actions, whichever comes first, Amgen shall have the right to bring and control any such action at its own expense and by counsel of its own choice, and Isis shall have the right, at its own expense, to be represented in any such action by counsel of its own choice. (e) Except as otherwise agreed to by the parties as part of a cost-sharing arrangement, any recovery realized as a result of any such litigation described in Sections 9.4(b), 9.4(c) and 9.4(d) above (after reimbursement of reasonable attorneys' fees and litigation expenses of Isis and Amgen) shall be retained by the party that brought and controlled such litigation for purposes of this Agreement, except that any recovery realized by a party as a result of such litigation, after reimbursement of the parties' reasonable attorneys' fees and litigation expenses, shall, to the extent attributable to lost profits based on sales of Products, be allocated between the parties so as to [***]. 23. 9.5 INFRINGEMENT OF THIRD PARTY RIGHTS. Each party will promptly notify the other in writing of any allegation by a Third Party that the activity of either of the parties pursuant to this Agreement infringes or may infringe the intellectual property rights of such Third Party. Other than with respect to any claim for which Amgen has an indemnification obligation under Section 13.1(a), Isis shall have the sole right to control any defense of any such claim involving alleged infringement of Third Party rights by Isis' activities at its own expense and by counsel of its own choice, and Amgen shall have the right, at its own expense, to be represented in any such action by counsel of its own choice.

ARTICLE 13 INDEMNIFICATION 13.1 INDEMNIFICATION. (a) During the Term and for a period of ten (10) years after the Term, Amgen hereby agrees to save, defend, indemnify and hold harmless Isis and its officers, directors, employees, consultants and agents from and against any and all losses, damages, liabilities, expenses and costs, including reasonable legal expenses and attorneys' fees ("LOSSES"), to which Isis may become subject as a result of any claim, demand, action or other proceeding by any Third Party to the extent such Losses arise directly or indirectly out of: (a) the breach of any representation or warranty made by Amgen pursuant to Article 10; (b) any material breach of this Agreement by Amgen; (c) the practice by Amgen of any license granted hereunder (other than with respect to any claims by [***] or [***] with respect to the subject matter of the [***] License and the [***] License); (d) the development, manufacture, use, handling, storage, sale or other disposition of any Collaboration ASO Compound, Amgen ASO Compound or Product by Amgen, its Affiliates or Sublicensees; (e) any Third Party claim that either party's use of an Amgen Gene Target infringes the intellectual property rights of such Third Party; or (f) violation of the trade secrets of any Third Party by Amgen; except, in each case, to the extent such Losses result from the gross negligence or willful misconduct of Isis or from the breach of any representation or warranty hereunder by Isis. (b) During the Term and for a period of ten (10) years after the Term, Isis hereby agrees to save, defend, indemnify and hold harmless Amgen and its officers, directors, employees, consultants and agents from and against any and all Losses to which Amgen may become subject as a result of any claim, demand, action or other proceeding by any Third Party to the extent such Losses arise directly or indirectly out of: (a) the breach of any representation or warranty made by Isis pursuant to Article 10; (b) any material breach of this Agreement by Isis; (c) the practice by Isis of any license granted hereunder; (d) the development, manufacture, use, handling, storage, sale or other disposition of any product by Isis, its Affiliates or sublicensees; or (e) violation of the trade secrets of any Third Party by Isis; except, in each case, to the extent such Losses result from the gross negligence or willful misconduct of Amgen or from the breach of any representation or warranty hereunder by Amgen. 13.2 CONTROL OF DEFENSE. In the event a party (the "INDEMNIFIED PARTY") seeks indemnification under Section 13.1, it will inform the other party (the "INDEMNIFYING PARTY") of a claim as soon as reasonably practicable after it receives notice of the claim, it will permit the Indemnifying Party to assume direction and control of the defense of the claim (including the right to settle the claim solely for monetary consideration), and will cooperate as requested (at the expense of the Indemnifying Party) in the defense of the claim; PROVIDED HOWEVER, that the Indemnified Party shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnified Party, if representation of such Indemnified Party by the counsel retained by the Indemnifying Party would be inappropriate due to actual or potential differing interests between such Indemnified Party and any other party represented by such counsel in such proceedings. The indemnity obligation in this Article 13 shall not apply to amounts paid in settlement of any loss, liability, damage, expense, claim, demand, action or other proceeding by 36. the Indemnified Party if such settlement shall be effected without the consent of the Indemnifying Party, which consent shall not be unreasonably withheld. The failure by the Indemnified Party to deliver notice to the Indemnifying Party within a reasonable time after commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such Indemnifying Party of any liability to the Indemnified Party under this Section 13.2, but the omission to deliver notice to the Indemnifying Party will not relieve the Indemnifying Party of any liability that it may have to the Indemnified Party other than under this Section 13.2. The Indemnified Party under Section 13.2 and its employees and agents shall cooperate reasonably with the Indemnifying Party and its legal representatives in the investigation of any action, claim or liability covered by this indemnification. 13.3 INSURANCE. Each party, at its own expense, will maintain product liability insurance (or self-insure) in an amount consistent with industry standards during the Term and will name the other party as an additional insured with respect to such insurance. Each party will provide the other party with a certificate of insurance (or evidence of self-insurance) evidencing such coverage. ARTICLE 14 DISPUTE RESOLUTION 14.1 DISPUTES. Isis and Amgen shall deal with each other in good faith. The parties recognize that disputes as to certain matters may from time to time arise which relate to either party's rights and/or obligations hereunder. It is the objective of the parties to establish procedures to facilitate the resolution of such disputes in an expedient manner by mutual cooperation and without resort to litigation. To accomplish this objective, the parties agree to follow the procedures set forth in Section 14.2, if and when such a dispute arises between the parties. 14.2 PROCEDURES; DISCUSSIONS BETWEEN THE PARTIES. If any claim, dispute or controversy of whatever nature arises out of or relating to this Agreement including, without limitation, any action or claim based on tort, contract or statute (including any claims of breach or violation of statutory or common law protections from discrimination, harassment and hostile working environment), or concerning the interpretation, effect, termination, validity, performance and/or breach of this Agreement ("CLAIM"), arises between the parties and the parties cannot resolve the dispute within thirty (30) days after written notice of a Claim by a party, at the written request by either party to the other party, the parties agree to hold a meeting, attended by the Chief Executive Officer of Isis and the Executive Vice President, R&D or another Amgen officer appointed by the Executive Vice President, R&D of Amgen, to attempt in good faith to negotiate a resolution of the dispute prior to pursuing other available remedies. If, within thirty (30) days after such written request, the parties have not succeeded in negotiating a resolution of the dispute, such dispute may be resolved by litigation. Notwithstanding the foregoing, either party may at any time make a claim for temporary or immediate equitable relief without following the foregoing procedure. 37.

This fixed percentage discount is also to be used by the POSC to guide its pricing decisions relevant to changes to MOE Oligonucleotide specifications, including specifically changes to purification, analytical, loading, shipping or handling specifications. Appendix B illustrates the application of this fixed percentage discount to Primer-Probe Sets and MOE Oligonucleotides using IDT List Prices. 4.4 EXTERNAL FACTORS & PRICE INCREASES. IDT warrants that it has performed adequate manufacturing cost-forecasting to ensure that IDT can supply Program Oligonucleotides in commercially viable fashion at the above quoted per base prices or at the established [***] discount. However, should unforeseeable events beyond the control of IDT cause the manufacturing costs of IDT to increase by [***] then IDT shall have the right to 6 increase the per [***] price to reflect the increased manufacturing cost. The term "unforeseeable events" as used in this paragraph includes, but is not limited to: (i) new and substantial regulatory or legal restrictions imposed on the manufacture of oligonucleotides or related manufacturing processes; (ii) substantial increase(s) in the cost of necessary oligonucleotide manufacturing amidites, reagents, solvents, or quality control components, necessary to manufacture Program Oligonucleotides; Should IDT rely upon "unforeseeable events" beyond the control of IDT as a basis for a price increase, IDT shall immediately as is practical disclose in writing to ISIS through the POSC the cause of the price increase, and IDT's relevant manufacturing costs in sufficient detail to allow for confirmation of the costs by ISIS. 4.5 PRICE DECREASES/MOST FAVORED PRICING. If there are substantial decreases in the market cost of commercial amidites, reagents, solvents, or quality control components necessary to manufacture Program Oligonucleotides that result in [***] or greater reduction in the average cost [***] to IDT, then IDT shall reduce the [***] price charges to ISIS by the amount greater than the [***] cost per base threshold. 4.6 TURNAROUND. The specifications and requirements for delivery of manufacture of Program Oligonucleotides will be those specifications and turnaround requirements identified in Appendix A, as amended from time-to-time by the POSC. 4.7 SUPPLY FORECASTS/ISIS SUPPLIED REAGENT INVENTORY. On or before the [***] of each month during the Assigned Supply Period, ISIS will supply IDT with a forecast of its intended Program Oligonucleotide orders for the following month. IDT will advise ISIS within [***] Days of receipt of its ability to meet the forecast. IDT will specifically advise ISIS of its then current inventory of ISIS Supplied Reagents and of its need for additional ISIS Supplied Reagents to meet the forecast for the following month. It is the expectation of both Parties that IDT will: (i) maintain on-site, a constant minimum [***] inventory of quality-controlled ISIS Supplied Reagents; (ii) maintain available manufacturing capacity to meet any forecast that requires a monthly MOE Oligonucleotide supply of [***] MOE Oligonucleotides or less, and a monthly Quantification Oligonucleotide supply of [***] Primer-Probe Sets or less; (iii) make reasonable efforts to meet forecasts that exceed those limits in (ii) above. In the event that an ISIS forecast is for volumes of Program Oligonucleotides, which volumes are [***] greater than the prior month, then IDT's ability to meet such a forecast may require a scale-up period. 7 4.8 INVOICING. During the Assigned Supply Period, IDT will invoice ISIS following the close of each month in accordance with 2.5 herein, for Program Oligonucleotides delivered that meet the specifications established by the POSC. Payment of the invoice by ISIS will be due within [***] Days from receipt of the invoice by ISIS, and payment will be made by electronic wire transfer into an account as designated by IDT. Should ISIS fail to pay the full invoice within [***] Days, IDT will have the right to suspend Program Oligonucleotide manufacturing until the invoice is paid in full. 4.9 MOST-FAVORED QUANTIFICATION OLIGONUCLEOTIDE PRICING. In addition to IDT's commitment to maintain a fixed [***] discount for Quantification Oligonucleotides and Antisense Oligonucleotides, IDT agrees not to extend more favorable pricing to third-parties with comparable orders for Antisense Oligonucleotides and/or Probes, whether ordered individually or as part of a Primer-Probe Set. For purposes of this provision, "comparable orders" shall mean orders for oligonucleotides in equal or lesser volumes, on the same or substantially similar scale, with the same or substantially similar modifications, purification or purity requirements, analytical specifications, and loading requirements. This provision shall not apply to more favorable prices extended to third-parties by IDT for Primers ordered without corresponding orders for Probes, nor shall it apply to Probes, Primers, or Antisense Oligonucleotides when sold or transferred in any of the following non-limiting circumstances: as part of a bona-fide research collaboration; as a component of a kit; as part of a defined promotion; as a test-order; or as a remake. 4.10 CUSTOMER DEPOSIT DEPLETION. Unless IDT and ISIS agree in writing to extend the Agreement and the Assigned Supply Period, any unused portions of the Customer Deposit at the end of the Assigned Supply Period will be forfeited by ISIS and will become the exclusive property of IDT. ARTICLE 5 INTELLECTUAL PROPERTY 5.1 INVENTIONS AND DISCOVERIES. The Parties do not anticipate but do acknowledge that Intellectual Property may be developed through the joint efforts of the Parties and their employees under this Agreement. If Intellectual Property is developed by an individual Party, or by or through the joint efforts of the Parties, the ownership of the Intellectual Property, whether joint or separate, will be determined by the relevant applicable United States patent laws. In the event that an invention or know-how is developed through the joint or collaborative efforts of the Parties and their employees, IDT and ISIS agree to instruct their respective employees to report the invention or the development in a thorough and prudent manner to the management of the respective Parties, and each Party and agrees to notify the other Party of the invention or the development as soon as commercially practical following internal reporting. The Parties thereafter agree to initiate good faith negotiations directed toward the completion of a separate written agreement directed to licensing and/or assignment of such Intellectual Property. 8 5.2 TRADENAMES AND TRADEMARKS. IDT acknowledges that GeneTrove-TM- and ISIS, among others, are trademarks and tradenames of ISIS, and that nothing in this Agreement is intended as a grant to IDT, express, implied, or otherwise, to use any trademark, tradename or trade dress of ISIS unless expressly agreed to in writing by ISIS. 5.3 PROGRAM OLIGONUCLEOTIDES AND OLIGONUCLEOTIDE MANUFACTURING METHODS. Notwithstanding the provisions of paragraph 5.1, ISIS shall be the sole owner of the Program Oligonucleotides, which are or contain the Confidential Information of ISIS and subject to the provisions of Article 7. Except with respect to patents and patent applications exclusively licensed to IDT in the field of antisense technology, IDT hereby assigns its entire worldwide right, title, and interest, if any, in any Program Oligonucleotide to ISIS, and IDT agrees to take all necessary action to effect any such transfer, and to cooperate with and assist ISIS, at ISIS's expense, in the pursuit, enforcement, and defense of any Intellectual Property rights in any Program Oligonucleotide.

Each Party may use the other Party's Confidential Information only for the purpose of performing each Party's duties and obligations under this Agreement. 7.5 OBLIGATIONS OF CONFIDENTIALITY. Except as expressly provided herein, ISIS and IDT, and their officers, employees, agents, consultants, and authorized representatives (a) shall hold in strict confidence all Confidential Information from the other Party or any of its officers, employees, agents or representatives and (b) shall not distribute, disclose or disseminate such Confidential Information to any third party without the prior written approval of the other Party (that is, the original disclosing Party), provided, however, that such approval will not be unreasonably withheld where the receiving Party reasonably believes that disclosure of the other Party's Confidential Information is reasonably necessary to obtain patents, authorization to conduct clinical trials, or regulatory approval. 7.6 OTHER INFORMATION. For purposes of this section, information will not be considered to be Confidential Information of a Party if the information: (i) was lawfully in the receiving Party's possession prior to disclosure under this Agreement and was not acquired directly or indirectly from the disclosing Party; or, (ii) was, at the date of disclosure by the disclosing Party, public knowledge; or subsequently becomes public knowledge other than through the failure of the receiving Party to comply with its obligations of confidentiality under the terms of this Agreement; or, (iii) was or is acquired by the receiving Party from any third party lawfully having possession of such information and who is not under an obligation of confidentiality to the disclosing Party; or, 12 (iv) was or becomes independently known by the receiving Party without utilizing information provided by the disclosing Party and wherein such independent knowledge is supported in contemporaneously written and dated documentation of the receiving Party; or, (v) is required to be disclosed, retained, or maintained by either Party, by applicable law or regulation or under the rules of any regulatory or governmental authority, including specifically federal district courts; provided however that each Party shall immediately notify the other Party in writing of such required disclosure and must provide such notice at least thirty (30) days prior to the date when disclosure is proposed to take place, and provided that the Party or third party required to make disclosure shall use its best efforts to secure confidential treatment of any such information required to be disclosed. 7.7 ADDITIONAL REMEDIES. The Parties hereto understand and agree that remedies at law may be inadequate to protect against any breach of any of the provisions of this Article 7 by either Party or their employees, agents, officers or directors or any other person acting in concert with it or on its behalf. Accordingly, each Party shall be entitled to the granting of injunctive relief by a court of competent jurisdiction against any action that constitutes any such breach of this Article 7. 7.8 EXTENDED TERM. The provisions of this Article 7 shall survive any termination or expiration of this Agreement and continue in force for a period of [***] years. ARTICLE 8 TERM AND TERMINATION 8.1 TERM. The term of this Agreement will be from the Effective Date and will continue for a period of eight (8) years from the Effective Date, unless earlier terminated by a Party or the Parties under one of the provisions of this Article 8. 8.2 BANKRUPTCY. This Agreement shall terminate upon written notice subject to paragraph 10. 4, by one Party to the other Party in the event the other Party shall become insolvent, asks its creditors for a moratorium, files a bankruptcy petition, or suffers appointment of a temporary or permanent receiver, trustee, or custodian, for all or a substantial portion of its assets. In the event of any termination pursuant to this provision, any unused Customer Deposit shall be immediately forfeited by ISIS, and shall become the exclusive property of IDT. 8.3 TERMINATION. Either Party may terminate this Agreement for default by the other Party in performing any of its material obligations under this Agreement by notifying the other Party in writing of such default and allowing the other Party [***] Days within which to cure such default, unless the default is the failure to pay money, in which case the defaulting Party shall have only [***] Days to cure such default after receiving written 13 notice of non-payment. If such default is not cured within [***] Days from receipt of such notice of default (or [***] Days in the case of non-payment of money owed), the non-defaulting Party may terminate this Agreement by written notice, subject to paragraph 10.4, to the defaulting Party. 8.4 ELECTIVE TERMINATION. ISIS may terminate this Agreement by providing IDT [***] days written notice if IDT materially fails to comply with any of the Program Oligonucleotide manufacturing or supply requirements set forth in Article 4 and in Appendix A, as amended from time to time. The Parties recognize and acknowledge that the production of Program Oligonucleotides conforming to the specifications is important to ISIS and is a material term of this Agreement, and further that time is of the essence with respect to ISIS's demand for Program Oligonucleotides. IDT's failure to materially produce and deliver Program Oligonucleotides to ISIS as set forth in Article 4 and in conformity with the specifications, is considered a material breach of this Agreement and must be cured to the satisfaction of ISIS within [***] Days of notice of the same to IDT by ISIS. Failure by IDT to cure such a breach within thirty [***] Days is grounds for ISIS's elective termination of this Agreement. In the event IDT refuses to supply Program Oligonucleotides to ISIS in accordance with Article 2 herein, and/or IDT refuses to cure a material breach of this Agreement, such acts shall constitute an elective termination by IDT, and in such events ISIS shall be entitled to a refund of its unused and outstanding Customer Deposit. 8.5 EFFECT OF EXPIRATION OR TERMINATION OF AGREEMENT. Within [***] days after expiration or termination (the date of termination will be the date upon which the [***] day notice period lapses) of this Agreement, each Party shall return to the other Party any and all Confidential Information (Article 7) provided by the other Party pursuant to this Agreement. ISIS shall have the right to obtain and use all Program Oligonucleotides for which ISIS has paid and that are in IDT's possession, or that are scheduled to be manufactured, at the time of termination. Except to the extent expressly provided to the contrary, the rights and obligations of the Parties pursuant to Articles 5,6,7 9, and 10, shall survive the expiration or termination of this Agreement. Any and all rights of IDT to payments accrued through expiration or termination as well as obligations of the Parties under firm orders for purchase and delivery of Program Oligonucleotides at the time of such expiration or termination shall remain in effect. IDT will have no obligation to sell and deliver Program Oligonucleotides to ISIS that have delivery dates more than thirty (30) Business Days after the date of termination, and in the case of termination under paragraphs 8.2 or 8.3, the terminating Party has discretion in electing whether firm orders will remain in effect. Upon expiration of this Agreement, or termination of this Agreement for reasons other than an IDT elective termination as defined in 8.4 herein, any unused Customer Deposit shall be forfeited by ISIS and will default to IDT. Upon termination of this Agreement under paragraphs 8.2, 8.3, or 8.4, or upon expiration of this Agreement under 8.1, IDT shall immediately transfer to ISIS possession of ISIS Supplied Reagents upon notice from ISIS of the final post-termination receipt of Program Oligonucleotides, if any. 14 ARTICLE 9 INDEMNIFICATION 9.1 INDEMNIFICATION.

In the event of any claim against the Indemnified Parties by any third party for which indemnification may be sought pursuant to this Agreement, the Indemnified Party shall promptly notify the Indemnifying Party in writing of the claim; provided that the failure to promptly notify the Indemnifying Party of such claim shall not result in the loss of rights of indemnification hereunder except to the extent that the Indemnifying Party was materially prejudiced by such failure. The Indemnifying Party shall assume, at its sole expense, the defense of the claim and its settlement. The Indemnified Parties shall cooperate with the Indemnifying Party and may, at their option and expense, be represented in any such action or proceeding. The Indemnifying Party shall not be liable for any litigation costs or expenses incurred by the Indemnified Parties. In addition, the Indemnifying Party shall not be responsible for the indemnification of any Indemnified Party arising from any negligent or wrongful acts by such Indemnified Party, or as the result of any settlement or compromise by the Indemnified Parties without the Indemnifying Party's prior written consent. The Indemnifying Party may not settle or compromise any matter without the consent of the Indemnified Parties unless such settlement or compromise imposes no obligations on the Indemnified Parties and does not restrict the rights of the Indemnified Parties. ARTICLE 10 GENERAL 10.1 GOVERNING LAW. This Agreement shall be construed and the respective rights of the Parties determined according to the laws of the State of New York (without regard to the conflict of law rules of any jurisdiction), except as regarding matters of intellectual property law, which shall be determined in accordance with the national intellectual property laws relevant of the intellectual property in question. 10.2 ASSIGNMENT.

                  Drug Development Sublicenses under the Walder Patents to
                  third-parties. In this instance, notwithstanding the
                  provisions of 3.2.2., IDT shall have the right to grant an
                  In-House FGTV Licenses under the Walder Patents as a part
                  of an Antisense Drug Development Sublicense.

                  Sublicense Holder to pay IDT, the initial sublicensing fees
                  and Royalties as established in Appendix A, attached, and
                  to comply with or fulfill all necessary reporting and
                  accounting obligations as defined in this Restated
                  Agreement. ISIS's initial license payments (specifically
                  the [***] payment and the optional [***] payment) made
                  under this provision will be creditable against initial
                  sublicensing fees and royalty payments owed to IDT pursuant
                  to the issuance of Antisense Drug Development Sublicenses.

         3.3.4    PRIOR LICENSES. ISIS acknowledges that prior to this First
                  Amendment, Hybridon Inc., and Epigenesis Pharmaceuticals,
                  Inc., have each obtained an Antisense Drug Development
                  Sublicense from IDT, the scope and validity of which is not
                  affected by the exclusive rights granted ISIS in paragraph
                  3.3 herein. IDT agrees that it shall not amend or expand
                  either of such licenses without ISIS's prior written
                  approval.

9.1      TERM. The term of this Restated Agreement shall extend until the
         last patent to expire included within the Walder Patents or Isis
         Academic Patents, whichever expires later.

9.2      TERMINATION FOR BREACH. In the event either party shall materially
         breach any of the terms, conditions and agreements contained in this
         Restated Agreement, then the alleging party may, at its election,
         notify the other party of the alleged breach giving the other party
         thirty (30) days written notice to cure the breach or begin good
         faith negotiations to resolve such alleged breach. If the alleged
         breach is not resolved to the satisfaction of the alleging party
         within thirty (30) days of the first giving of notice the alleging
         party may, at its option, bring arbitration proceedings under
         Article 12. In the event of a good faith dispute about monetary
         obligations, the notified party will pay any undisputed amounts to
         the alleging party and pay any disputed amounts into escrow pending

         concern, then the other Party shall have the right but not the
         obligation to terminate the licenses granted by the termination
         party in this Restated Agreement; provided however, that Isis hall
         have the right to grant to its sublicensee(s), the power to assume
         Isis's rights and obligations under its licenses, and
         correspondingly Isis, and its successor in interest, however
         organized, shall, to the extent permitted by law, maintain the
         licenses granted to IDT pursuant to this Restated Agreement.

                  Agreement is terminated by a Party hereto or its receiver
                  or trustee under applicable bankruptcy laws due to such
                  Party's bankruptcy, then all rights and licenses granted
                  under or pursuant to this Restated Agreement by such Party
                  to the other Party are, and will otherwise be deemed to be,

                  hereunder, including without limitation any patents or
                  patent applications in any country of a Party covered by
                  the license grants under this Restated Agreement, are part
                  of the "intellectual property" as defined under Section
                  101(35A) of the Bankruptcy Code subject to the protections
                  afforded the non-terminating Party under Section 365(n) of
                  the Bankruptcy Code, and any similar law or regulation in
                  any other country.

         faith negotiations. Except with respect to disputes as to the
         validity of patents, applications for injunctions, specific
         performance, or other equitable relief, any dispute arising out of
         or in connection with this Restated Agreement or any legal
         relationship associated therewith, that cannot be resolved amicably
         by the parties, shall be finally resolved by arbitration. The
         arbitration shall be conducted in accordance with the arbitration
         rules of the American Arbitration Association ("AAA") then in force,
         by one or more arbitrators appointed in accordance with said rules;

         instituted until the party alleging breach of this Restated
         Agreement by the other party has given the other party not less than
         sixty (60) days notice to remedy any alleged breach and the other
         party has failed to do so. The place of arbitration shall be Cedar
         Rapids, Iowa, if Isis institutes the proceeding, and San Diego,
         California, if IDT institutes the proceeding. The award rendered
         shall be final and binding upon both parties. The judgment rendered
         shall include costs of arbitration, reasonable attorney's fees and

         application may be made to such court for judicial acceptance of the
         award and/or an order of enforcement. Disputes as to the validity
         and scope of patents shall be resolved by the courts of appropriate
         jurisdiction.

         if such deletion is allowed by relevant law, and the remaining terms
         and conditions of this Restated Agreement shall remain in full force

         as similar in effect to the present terms of this Restated Agreement
         as may be allowed under the applicable laws and regulations. The

         God, or any other event or cause beyond the control of the party
         claiming the benefit of this paragraph and which that party could

         assigned by either party without the prior written consent of the
         other party, except that either Party may freely assign this

                            INTRODUCTION AND OVERVIEW

       ISIS possesses proprietary technology and expertise related to antisense
drug discovery and the development of antisense including target validation and
gene functionalization.

       ATL is interested in using antisense for developing and discovering
antisense drugs.

      ATL and ISIS desire to collaborate to enable ATL to develop and
commercialize antisense drugs, on the terms and conditions set forth herein. In
essence, ISIS and ATL are jointly creating a new company focused on the
discovery and development of antisense therapeutic drugs.

      In support of the foregoing, ISIS will license ISIS 107248 to ATL, as the
first Collaboration Compound hereunder, for development and commercialization
and will work together with ATL to discover antisense drugs to additional gene
targets and grant ATL licenses to intellectual property related to ISIS'
antisense technology necessary to develop and commercialize such drugs. In
addition, ISIS will manufacture active pharmaceutical ingredient ("API") for use
in preclinical and clinical studies during the collaboration term. ATL will be
responsible for all of its other manufacturing needs, including the manufacture
of Product. ISIS will provide contract and consulting services for ATL for
preclinical studies and will provide various other services in support of
activities hereunder.

      In consideration for the licenses and other services provided by ISIS, ATL
will grant ISIS pre-IPO common shares in ATL pursuant to the related Stock
Purchase Agreement and will reimburse ISIS on a cash basis for contract service
work performed by ISIS during the term of the collaboration. ATL will be
responsible for developing, marketing, selling, and distributing all Products
that arise from the collaboration and will pay ISIS certain royalty payments on
sales of such Products.

      In connection with the collaborative and development activities described
herein, the parties will also enter into the related Clinical Supply Agreement
pursuant to which ISIS will supply ATL with API.

                                       1



      Therefore, in consideration of the foregoing premises and the mutual
covenants herein contained, the parties hereby agree as follows.

                                    AGREEMENT


                                    ARTICLE 1

                                   DEFINITIONS

      Capitalized terms used in this Agreement have the meanings set forth in
Exhibit 1.


                                    ARTICLE 2

                            DRUG DEVELOPMENT PROGRAM

2.1   GENERAL.

Under the Drug Development Program, ATL will develop and commercialize antisense
drugs arising out of the Collaborative Research Program conducted hereunder as
well as ISIS 107248, a Collaboration Compound discovered by ISIS. In general,
ATL will be responsible for all development and commercialization activities for
Collaboration Compounds. ISIS will initially perform preclinical activities
(IND-supporting toxicology) for ISIS 107248, but it is the intent of the parties
that ATL will assume responsibility for all preclinical and IND-enabling
activities with respect to subsequent Collaboration Compounds, as more
specifically provided in this Agreement. Other than certain consulting services
to be provided by ISIS to ATL hereunder at no charge, ATL will be responsible
for all costs of development and commercialization of Collaboration Compounds
including, without limitation, the reimbursement of ISIS' expenses as provided
herein. Because ISIS 107248 is a Collaboration Compound discovered by ISIS and
licensed to ATL hereunder, ISIS will be heavily involved in the development
plans for ISIS 107248. With regard to future Collaboration Compounds, it is the
parties' intent that, subject to meeting the Development Milestones, ATL will
proceed with considerably more autonomy.

2.2   ISIS 107248 DEVELOPMENT PLAN.

(a)   The plan for the development of ISIS 107248, including the roles and
      responsibilities of the parties, is contained in Exhibit 2.2 (the
      "ISIS 107248 Development Plan").  ATL will use commercially
      reasonable efforts to develop ISIS 107248 to maximize its commercial
      value. ISIS will use commercially reasonable efforts to assist ATL
      pursuant to the Development Plan. Each party will conduct its
      portion of the ISIS 107248 Development Plan in a good scientific
      manner and in compliance in all material respects with all
      requirements of applicable laws, rules and regulations to achieve
      the objectives efficiently and expeditiously. Each party will
      proceed diligently with its projects set out in the ISIS 107248
      Development

                                       2



      Plan using commercially reasonable efforts to provide sufficient time,
      effort, equipment, facilities and skilled personnel.

(b)   The target that is modulated by ISIS 107248 is CD49d, which is a Research
      Target hereunder and is listed in Exhibit 3.4.

(c)   ISIS 107248 DEVELOPMENT MILESTONES.  ATL commits to reach the
      following milestones in the development of ISIS 107248.

      (i)   MILESTONES:

            (A)   File IND (or analogous AU application) not later than
                  December 31, 2002;

            (B)   Initiate Phase I studies not later than the first
                  quarter of 2003;

            (C)   Initiate Phase IIa studies not later than December 31,
                  2004;

            (D)   Initiate Phase III studies not later than December 31,
                  2007;

            (E)   File an NDA not later than 18 months after the successful
                  completion of a pivotal trial; and

            (F)   Use commercially reasonable efforts to bring ISIS 107248
                  Product to market and maximize the commercial value of such
                  Product worldwide.

      (ii)  Pursuant to the provisions of this Agreement and the Joint
            Development Plan, ISIS will conduct certain IND-enabling studies and
            will use commercially reasonable efforts to complete such studies
            prior to [***]. In addition, ISIS will supply API ordered by ATL
            pursuant to the Clinical Supply Agreement.

      (iii) If ATL will not be able to meet the milestone set forth in (i)(A)
            above due to a delay on the part of ISIS in completing the studies
            referenced in (ii) or if ISIS is unable to meet its obligations to
            supply API ordered by ATL pursuant to the Clinical Supply Agreement,
            the [***].

      (iv)  Except as provided otherwise in (v) below, if ATL fails to meet any
            of the ISIS 107248 Development Milestones, the License to Research
            applicable to ISIS 107248 will immediately terminate.

      (v)   If a Development Milestone is not met, but ATL has proceeded in good
            faith and the Development Milestone was missed for circumstances
            beyond ATL's control, [***]. If the JDC cannot agree on this issue,
            the matter will be referred to the designated officers of ATL and
            ISIS for resolution, consistent with the provisions of Section
            16.6(a).

2.3   ADDITIONAL DEVELOPMENT ACTIVITIES.

(a)   GENERAL.

                                       3



      (i)   As provided herein, during the term of this Agreement, ATL
            will advance additional Collaboration Compounds through the
            various stages of an Active Program hereunder, i.e., from the
            research phase through preclinical and IND-enabling studies to
            human clinical studies and commercialization.  To maintain any
            Collaboration Compound in Active Development status, ATL must
            meet the Development Milestones for each such Collaboration
            Compound.

      (ii)  The terms under which ISIS and ATL will collaborate to develop such
            additional Collaboration Compounds will be in accordance with the
            terms set forth herein. Within [***] days of ATL's providing written
            notice to ISIS that ATL has initiated IND enabling studies on a
            Collaboration Compound, ATL will prepare a mutually-agreed-upon
            Development Plan for that Collaboration Compound, with ISIS'
            assistance, consistent with the terms of this Agreement.

(b)   IND-ENABLING STUDIES.  While it is the intent of the parties that
      ATL will assume responsibility for all preclinical and IND-enabling
      activities with respect to Collaboration Compounds other than ISIS
      107248, ISIS will be available to assist with the management of, or
      provide consulting support for, IND-enabling toxicology studies on
      up to [***] Collaboration Compounds following ISIS 107248, if
      requested to do so by ATL.  Should ATL request ISIS' assistance in
      this regard, the parties will agree on terms pertaining to ISIS'
      participation, which terms will be included in the Development Plan
      referenced in (a). With the possible exception of ISIS 107248 and an
      IGF-1R Collaboration Compound, ISIS will not be requested to
      participate in the conducting, management or support of IND-enabling
      toxicology studies for more than one Collaboration Compound at a
      time.

2.4   ANNUAL REPORTS.

ATL will provide ISIS with an annual written report describing all activities
performed by the parties and the results achieved during the relevant year with
respect to each Collaboration Compound in Active Development hereunder
including, without limitation, ISIS 107248. Each such report will include
details regarding the stage of development a Collaboration Compound has reached
within an Active Program including, without limitation, what Development
Milestones have been achieved. To the extent that it is feasible to do so, ATL
will also include the projected goals and Development Milestones it anticipates
achieving during the coming year with respect to such Collaboration Compound in
each such report.

2.5   COMMERCIALIZATION.

(a)   ATL will use commercially reasonable efforts to bring Products into
      commercial use as quickly as is reasonably possible, in a manner
      designed to maximize the commercial potential of such Products
      worldwide.  Prior to the launch of any Product, ATL will prepare a
      global integrated Product plan outlining the key aspects of market
      launch and commercialization (the "Integrated Product Plan" or
      "IPP"). Each IPP will be updated annually in accordance with ATL's
      internal planning and budgeting process.  ATL will provide ISIS a
      copy of the final draft of each IPP (original and updates) for each
      Major

                                       4



      Market.

(b)   Each IPP will also include appropriate milestones and the dates upon
      which such milestones must be met by ATL.  If ATL prepares and
      manages or carries out the IPP, ATL will use commercially reasonable
      efforts to Manufacture, market, promote, distribute, and sell the
      Product on a worldwide basis.  ATL will provide resources and expend
      funds in connection with such activities in a manner and to an
      extent comparable to the efforts of similar companies that
      manufacture, market, and sell pharmaceutical products of similar
      commercial potential at a similar stage of the product life cycle.

(c)   If a Sublicensee of ATL bears primary responsibility for preparing,
      managing and carrying out the IPP, the sublicense agreement will
      require that such Sublicensee will use commercially reasonable
      efforts to Manufacture, market, promote, distribute, and sell the
      Product on a worldwide basis and will require that the Sublicensee
      provide resources and expend funds in connection with such
      activities in a manner and to an extent comparable to the efforts of
      similar companies that manufacture, market, and sell pharmaceutical
      products of similar commercial potential at a similar stage of the
      product life cycle.  In addition, the IPP to be carried out by such
      Sublicensee will include appropriate milestones and the dates upon
      which such milestones must be met, as approved by ISIS in advance,
      which approval will not unreasonably be withheld.

(d)   Consistent with Section 4.3 below, if ATL elects to meet any of its
      responsibilities and obligations under this Section via sublicense
      agreements, ATL will ensure that such agreements are subject to and will
      be consistent with the terms and conditions of this Agreement including,
      without limitation, the provisions of this Section.

(e)   If ATL or a Sublicensee of ATL anticipates any difficulty in meeting its
      commercialization obligations under this Section including, without
      limitation, the milestones set forth in the IPP, ATL or its Sublicensee
      will provide ISIS with prompt notice thereof, in order that the parties
      may endeavor to work out an appropriate and acceptable resolution prior to
      pursuing other remedies hereunder.


                                    ARTICLE 3

                         COLLABORATIVE RESEARCH PROGRAM


3.1   GENERAL; COLLABORATION TERM.

(a)   ATL and ISIS will work together under the Collaborative Research
      Program described herein and as further detailed in the
      Collaborative Research Plan, as described in Section 3.2, to
      discover and develop antisense therapeutics.  The parties will
      collaborate to assess Research Targets that may be important in the
      prevention or treatment of a disease or condition, consistent with
      Sections 3.2 - 3.5.  ISIS will discover and design antisense
      oligonucleotides to modulate the Research Targets as provided in
      Section 3.7 and will

                                       5



      provide them to ATL; also, if contracted by ATL, will evaluate the
      antisense oligonucleotides in various functional assays.  ATL will
      perform IN VITRO and IN VIVO studies utilizing the antisense
      oligonucleotides provided by ISIS.  ISIS may perform additional studies,
      at ATL's request and expense, with the antisense oligonucleotides as
      part of a GeneTrove Investigation to better understand a particular
      Research Target's role in a specific biological pathway, as further
      described in Section 3.8.  It is the intent of the parties that
      Collaboration Compounds will be identified during the Collaboration Term
      and that pursuant to Active Programs hereunder, such Collaboration
      Compounds will progress through research and preclinical development,
      meeting the relevant Development Milestones (see Exhibit 1, Section 1.2)
      and will each become the focus of a Development Plan hereunder.

(b)   The Collaboration Term will begin on the Effective Date and will continue
      for 5 years unless earlier terminated due to termination of the Agreement
      under Sections 12.2 or 12.3, or unless terminated or extended upon mutual
      agreement of the parties.

3.2   JOINT RESEARCH COMMITTEE.

(a)   Within [***] days of the Effective Date, the parties will create a
      Joint Research Committee of 4 people to facilitate the research
      collaboration called for herein. The JRC will consist of 2
      representatives nominated by each party. Each party will designate a
      representative as a project leader to serve as the principal contact
      person for that party.  The parties may agree to add additional
      members to the JRC, as long as equal representation is maintained.
      [***].

(b)   During the Collaboration Term, the JRC will be the primary vehicle
      for interaction between the parties with respect to the
      collaborative research conducted hereunder. The JRC will be
      responsible for preparing an annual budget and plan for the
      collaborative research activities to be conducted during each year
      of the Collaborative Research Program (the "Collaborative Research
      Plan") and for managing that program.  The JRC will be responsible
      for updating the Collaborative Research Plan as needed and will also
      be responsible for determining the order in which Research Targets
      are prioritized for Gene Walks.

(c)   The JRC will meet as needed during the Collaboration Term. Meetings
      will be via teleconference or videoconference, or as the parties may
      otherwise agree. The JRC will review the progress of the activities
      carried out under the Collaborative Research Program and will
      consider and decide on proposed modifications to the strategy and
      goals of that program.  The frequency, dates and times of all
      meetings will be mutually agreed upon by the parties. At its first
      meeting the JRC will determine such procedures as it will reasonably
      require to conduct its business.

3.3   RESEARCH TARGETS:  GENERAL.

As noted above, ATL and ISIS will collaborate to assess Research Targets that
may be important in the prevention or treatment of a disease or condition.

                                       6



3.4   RESEARCH TARGETS:  DESIGNATION.

(a)   The collaborative research hereunder will be focused on specific gene
      targets thought to be attractive for the development of antisense drugs.
      ATL will choose targets in accordance with the provisions of this Section
      3.4 as the basis for its antisense drug discovery efforts. ATL commits to
      use commercially reasonable efforts to conduct research and drug discovery
      activities with respect to each Research Target to maximize its commercial
      value.

(b)   Exhibit 3.4 hereto contains a list of the initial targets that are
      the object of Licenses to Research (the "Research Targets"), as well
      as the nucleic acid sequences for the corresponding human genes and
      a brief record of any studies performed on those targets by ISIS.
      Research Targets listed on Exhibit 3.4 that are Dermatology Targets
      are listed in Section B, and all other Research Targets are listed
      in Section A of Exhibit 3.4.  During the Collaboration Term, targets
      may be added to and removed from Exhibit 3.4 in accordance with the
      terms of this Section and Section 3.5.

3.5   RESEARCH TARGETS:  SELECTION, REMOVAL, REPLACEMENT AND APPROVAL
      PROCESS.

(a)   As noted above, on the Effective Date, Exhibit 3.4 will list the
      initial Research Targets agreed upon by the parties.  ATL warrants
      and represents that if it has not provided ISIS with the nucleic
      acid sequences for the corresponding human genes for any of the
      Research Targets listed in Exhibit 3.4 by the Effective Date, it
      will do so promptly thereafter.  Consistent with the terms of this
      Agreement, ISIS will have no obligation to conduct any activities
      with respect to such Research Targets until the required materials,
      information and/or payments (if applicable) have been submitted to
      ISIS by ATL. The addition of new Research Targets to the list in
      Exhibit 3.4 is at ISIS' sole discretion.


(b)   If ATL wishes to designate a new Research Target, it will provide
      ISIS with written notice of the target it wishes to add to the list
      set forth in Exhibit 3.4.  Such written notice will include the gene
      name, the NCBI accession number or nucleic acid sequence, and one or
      more mammalian cell lines that express the Research Target.  ISIS
      will not, and is not required to, accept a proposed Research Target
      without such information.  In addition, ATL will inform ISIS of
      whether or not to the best of ATL's knowledge the proposed target is
      in the public domain or is proprietary to a Third Party.

      (i)   ATL will not propose a target for consideration as a possible
            Research Target if to its knowledge ATL is not able to provide ISIS
            with rights to use such target sufficient to enable ISIS to carry
            out its activities in support of the Collaborative Research Program
            as contemplated by the parties hereunder.

      (ii)  If ATL proposes a target that is encumbered by Third Party
            restrictions, [***].

      (iii) If a target proposed by ATL is subject to an ISIS drug discovery and
            development program or a contractual obligation of ISIS to a Third
            Party with respect to that target, then the proposed target will not
            be approved as a Research Target hereunder.

                                       7



(c)   Within [***] days after receipt of the ATL notice under subsection (b),
      ISIS will notify ATL, in writing, of its decision either to approve or to
      reject a proposed target.

      (i)   If a proposed target is not approved as a Research Target, the
            notice provided by ISIS will advise ATL of the reason(s) the target
            was not approved, and ATL will be invited to submit a different
            proposed target for consideration.

      (ii)  If a proposed target is approved as a Research Target, ISIS' notice
            to ATL will indicate this and will also indicate whether or not the
            new Research Target is a Dermatology Target. ISIS will add the
            Research Target to the list in Exhibit 3.4 (as well as the nucleic
            acid sequence of the gene) and will provide ATL with an amended copy
            of Exhibit 3.4. If ISIS has performed animal or other preclinical
            studies on any antisense molecule that modulates the newly-added
            Research Target, or has established efficacy, ISIS will add that
            information to Exhibit 3.4 and will provide ATL with a copy of the
            amended exhibit.

      (iii) Upon receipt of written notice from ISIS that a proposed target has
            been approved as a Research Target and added to Exhibit 3.4, ATL
            will begin Active Development of such Research Target, consistent
            with the terms of this Agreement.

(d)   After the Effective Date, Research Targets may be removed from the list in
      Exhibit 3.4 as follows.

      (i)   If ATL wishes to remove a Research Target from the approved list in
            Exhibit 3.4, it will provide ISIS with prompt written notice of its
            election to do so. Upon ISIS' receipt of such notice, it will remove
            the Research Target from the list.

      (ii)  Upon receipt of notice at any time during the term of this Agreement
            that a Research Target is no longer in Active Development, ISIS will
            remove the target from the list set forth in Exhibit 3.4 and will
            provide ATL with prompt written notice of same.

      (iii) The License to Research or License to Exploit applicable to any
            Research Target removed pursuant to (i) or (ii) herein (each an
            "Abandoned Research Target") will immediately terminate, consistent
            with the provisions of Sections 4.1 or 4.2, as applicable.
            Notwithstanding the foregoing, an Abandoned Research Target may
            still bear royalty or other payment obligations, as described in
            Sections 5.1 - 5.3 herein.

      (iv)  Once a target has been removed from the list of Research Targets,
            Exhibit 3.4 will be amended to delete such target and a copy of
            amended Exhibit 3.4 will be sent to ATL by ISIS.

      (v)   Upon termination of a License to Research or a License to Exploit
            for any reason, a Research Target will be automatically removed from
            Exhibit 3.4 and will thereafter be considered an Abandoned Research
            Target.

                                       8



(e)   At no time during the term of this Agreement or the Collaboration Term
      will there be any more than [***] designated Research Targets. As of the
      Effective Date, ATL may nominate up to [***] Research Targets; after the
      Effective Date, ATL may not substitute more than [***] Research Targets in
      any year during the Collaboration Term.

3.6   GENEWALKS; GENETROVE INVESTIGATIONS.

(a)   GENERAL OVERVIEW.  ISIS will perform Gene Walks on all of the
      Research Targets designated in Exhibit 3.4, with the exception of
      CD49d, as a Collaboration Compound for that Research Target has
      already been identified by ISIS (i.e., ISIS 107248).  The Gene Walks
      are expected to provide ATL with at least one optimized antisense
      oligonucleotide designed to modulate the respective Research Target
      together with control oligonucleotides.  Upon ATL's request, ISIS
      will then evaluate those antisense oligonucleotides selected for
      further study by ATL in functional assays.  ATL will utilize the
      antisense oligonucleotides further in IN VITRO and IN VIVO studies.
      A GeneTrove Investigation, which ATL may request after a Gene Walk
      for the relevant Research Target has been performed, includes the
      use of the antisense oligonucleotides that are obtained as a direct
      result of the Gene Walk in primary cellular phenotypic assays
      currently conducted by ISIS, as further described below and in
      Exhibit 3.8.  The ownership and use of all materials, including
      Antisense Inhibitors, and of all data and information generated as a
      result of a Gene Walk, a GeneTrove Investigation, or otherwise
      provided to ATL by ISIS pursuant to this Agreement, is governed by
      the provisions of Article 6.

(b)   PROJECT COORDINATORS.  ATL and ISIS will each select one employee to
      serve as the Project Coordinator for that party, with respect to
      Gene Walks and GeneTrove Investigations.   The Project Coordinators
      will facilitate the selection, prioritization, removal and
      replacement of Research Targets.  The Project Coordinators will each
      have appropriate technical credentials, knowledge and ongoing
      familiarity with the foregoing activities. The Project Coordinators
      will meet on an as-needed basis via teleconference or
      videoconference, at times mutually agreed upon by the parties.
      Decisions of the Project Coordinators will be unanimous.  If the
      Project Coordinators cannot agree on an issue, the issue will be
      submitted to the JRC for resolution.

3.7   GENE WALKS.

(a)   ISIS agrees to perform up to [***] Gene Walks on Research Targets
      for ATL during the Collaboration Term [***].  Gene Walks performed
      on genes of different species are considered separate Gene Walks;
      for example, a Gene Walk performed on a mouse gene and one performed
      on its human equivalent counts as two Gene Walks.  ATL may request
      that ISIS perform an additional [***] Gene Walks on Research Targets
      during the Collaboration Term, at a cost to ATL of [***] each.  If
      ISIS agrees to perform additional Gene Walks, ATL will compensate
      ISIS for the cost of each such additional Gene Walk [***].

                                       9



(b)   Irrespective of the timing of ATL's requests for Gene Walks - that
      is, whether or not ATL uses its allocation of [***] Gene Walks
      within the first [***] years of the Collaboration Term, and
      regardless of when ATL elects to use its allocation of [***] Gene
      Walks at [***] apiece - ISIS will not be required to perform more
      than [***] Gene Walks per year for ATL during the first [***] years
      of the Collaboration Term and will not be required to perform more
      than [***] Gene Walks per year for ATL during the remaining [***]
      years of the Collaboration Term.  Gene Walks, a sample Gene Walk
      schedule for the Collaboration Term, and the related activities of
      the parties are further described in Exhibit 3.7.

(c)   A Gene Walk is automatically requested when a Research Target is
      added to the list in Exhibit 3.4.  Therefore, as of the Effective
      Date, ATL will be deemed to have requested a Gene Walk for each
      Research Target listed in Exhibit 3.4, except for CD49d.  Within
      [***] days of the Effective Date, ATL will provide ISIS with written
      notice of the order in which it wishes the Research Targets to be
      scheduled for Gene Walks.  As new Research Targets are added to
      Exhibit 3.4, they will be added to the end of the list of targets on
      which Gene Walks are to be performed.

(d)   After each successful Gene Walk, ISIS will provide up to [***] Antisense
      Inhibitors and a control oligonucleotide to ATL for use in confirming
      studies in quantities not to exceed 2 (mu)mole per Research Target. ATL
      may request quantities for use in preclinical pharmacology studies at the
      price of [***] per order for amounts up to [***] of the particular
      Antisense Inhibitor ordered. [***]


3.8   GENETROVE INVESTIGATIONS.

(a)   ATL may request that ISIS perform up to [***] GeneTrove Investigations per
      year during the Collaboration Term on Research Targets at a cost to ATL of
      [***] per GeneTrove Investigation. GeneTrove Investigations and the
      related activities of the parties are further set forth in Exhibit 3.8.

(b)   ATL may request that ISIS perform additional GeneTrove Investigations. If
      ISIS agrees, at its sole discretion, to perform additional GeneTrove
      Investigations, ATL will compensate ISIS for each such additional
      GeneTrove Investigation in accordance with comparable rates charged by
      ISIS' GeneTrove division to other GeneTrove customers.

(c)   To request a GeneTrove Investigation under subsection (a) or (b) herein,
      ATL will submit a written request to ISIS, which request will indicate the
      identity of the Research Target on which ATL requests that a GeneTrove
      Investigation be performed. ATL will provide ISIS with any additional
      information reasonably requested by ISIS to enable ISIS to conduct such
      GeneTrove Investigation.

(d)   Except as provided otherwise herein, the data and information generated by
      the GeneTrove Investigations pursuant to the collaboration hereunder will
      be considered confidential and will be subject to the provisions of
      Article 6.


                                       10





(e)   ATL agrees that ISIS may enter data and information from ISIS' conduct of
      each GeneTrove Investigation for ATL hereunder into its proprietary human
      gene function database(s), [***].


3.9   OTHER COLLABORATIVE RESEARCH PROGRAM-RELATED ACTIVITIES.

(a)   ACCESS TO CONSULTING SUPPORT AND TRAINING.


      (i)   During the Collaboration Term, ISIS will provide ATL with reasonable
            amounts of preclinical and research advice [***] (phone consultation
            or visit at ISIS only) in support of any Active Program hereunder
            that involves a Collaboration Compound made using ISIS Standard
            Chemistry for which a License to Research exists.

      (ii)  During the first [***] years of the Collaboration Term, upon ATL's
            request and at times mutually agreed upon by the parties, ISIS will
            allow [***] visiting scientists from ATL to work in the ISIS
            laboratories to be trained in [***], during normal business hours
            and upon reasonable prior notice, subject to any restrictions
            imposed by ISIS in order to protect the confidentiality of programs,
            activities and information unrelated to any ongoing Active Program
            hereunder. The visiting scientists may visit and receive training at
            ISIS for up to [***]. ATL will pay all expenses (e.g. salary,
            travel, lodging, meals, transportation, etc.) incurred by its
            visiting scientists while receiving training from ISIS personnel. No
            ISIS personnel will be required to visit ATL's facilities.

      (iii) ISIS acknowledges that ATL may desire to train its academic
            collaborators. If ATL wishes to substitute an academic collaborator
            for an ATL employee with respect to the training referenced in (a)
            above, ATL will provide ISIS with a specific written request to do
            so in advance, for ISIS' approval, which approval will not
            unreasonably be withheld. Any such academic collaborator, once
            approved by ISIS, must enter into a confidentiality agreement with
            ISIS before any training can be initiated.

      (iv)  If ATL requests additional amounts or types of consulting support or
            training and if ISIS agrees to provide such training, the parties
            will negotiate appropriate terms including, without limitation, the
            scope, timing, duration and cost of such training, in good faith.

            dermatological indications only. These rights will only be
            sublicensable as explicitly provided in Section 4.3. The license
            granted hereunder will commence automatically on grant of the
            License to Research and will not terminate upon termination of the
            corresponding License to Research.

(b)   As of the Effective Date, ISIS grants to ATL a License to Research with
      respect to each Research Target listed in Exhibit 3.4. ATL will receive
      additional Licenses to Research with respect to Research Targets when
      added to Exhibit 3.4. Licenses to Research may only be obtained during the
      Collaboration Term. No License to Research will be granted to ATL on any
      Research Target after the Collaboration Term ends.

(c)   [***]

(d)   ATL may terminate a License to Research with respect to a Research Target
      for any reason, at any time during the term of this Agreement, by
      providing ISIS with written notice that the Research Target is being
      removed from Exhibit 3.4.

(e)   With the exception of the License to Research applicable to ISIS 107248,
      which is governed by the provisions of subsections (f) and (g) below, if a
      Research Target is no longer part of an Active Program, ISIS may terminate
      the License to Research applicable to that Research Target at any time
      during the term of this Agreement upon written notice to ATL.

                                       12



(f)   As provided in Section 2.2(c), ISIS may terminate the License to Research
      applicable to ISIS 107248 at any time during the term of this Agreement
      upon written notice to ATL, if the milestones or other conditions set
      forth in Section 2.2(c) are not timely met.

(g)   Once ATL has elected and obtained 5 Licenses to Exploit pursuant to
      Section 4.2, all remaining Licenses to Research will immediately
      terminate, and all rights to the remaining Research Targets licensed to
      ATL will revert to ISIS; provided, however, that the licenses granted
      pursuant to Section 4.1(a)(ii) will remain in effect.

(h)   ISIS will provide ATL with a semiannual report summarizing the status of
      Research Target Patent Rights subject to a License to Research hereunder
      and will include updates to any Exhibits that are affected.



4.2   LICENSES TO EXPLOIT. A License to Exploit is a license to perform
      research, development and commercialization activities on Products that
      modulate a Research Target.

(a)   ISIS grants ATL the option to convert any active License to Research
      hereunder into a License to Exploit, as set out below.
      Notwithstanding the foregoing, ATL may convert not more than 5
      Licenses to Research into Licenses to Exploit, and each License to
      Exploit must be requested by ATL prior to the filing of an NDA (or
      non-US equivalent) for the relevant Research Target.   The option to
      convert Licenses to Research to Licenses to Exploit expires [***]
      after the end of the Collaboration Term.

(b)   If ATL elects to convert a License to Research into a License to
      Exploit, ATL will provide ISIS with written notice effecting the
      exercise of the option, which will identify the particular Research
      Target to which the License to Research applies and will include
      written verification that all applicable milestones and obligations
      of ATL with respect to that Research Target have been timely met.
      Upon ISIS' receipt of such written notice, ISIS will have [***] days
      to object if it believes that ATL has not timely met all applicable
      milestones and obligations with respect to that Research Target.  At
      the end of such [***]-day period, the License to Exploit will be
      granted with respect to the relevant Research Target if ISIS has not
      objected. [***].

(c)   LICENSE GRANT.

      (i)   For each Research Target for which a License to Exploit is
            granted ISIS will grant to ATL an exclusive, worldwide license under
            the ISIS Core Technology Patent Rights, the ISIS Formulation Patent
            Rights, the Manufacturing Patent Rights, the Research Target Patent

            use, develop, offer for sale and sell Collaboration Compound
            Products that modulate such Research Target for all therapeutic and
            cosmetic applications. For Collaboration Compound Products that
            modulate Dermatology Targets, the license is limited to topical
            dermatological indications only. These rights will only be
            sublicensable as explicitly provided in Section 4.3. This license
            will commence automatically on grant of the corresponding License to
            Exploit and will terminate upon termination of the corresponding
            License to Exploit.

                                       13



      (ii)  For each Research Target for which a License to Exploit is
            granted ISIS will grant to ATL a nonexclusive worldwide license
            under the Research Target Patent Rights, the ISIS C5-Propyne Patent
            Rights, and the ISIS Formulation Patent Rights solely to make, have
            made, use, develop, offer for sale and sell Research Target Compound
            Products for all therapeutic and cosmetic applications. For Research
            Target Compound Products that modulate Dermatology Targets, the
            license is limited to topical dermatological indications only. These
            rights will only be sublicensable as explicitly provided in Section
            4.3. This license will commence automatically on grant of the
            corresponding License to Exploit and will not terminate upon
            termination of the corresponding License to Exploit.

(d)   No substitutions may be made on Licenses to Exploit. Once a License to
      Exploit has been taken with respect to a Research Target, a different
      Research Target may not be substituted thereunder.

(e)   ATL may terminate a License to Exploit with respect to a Research Target,
      for any reason, at any time during the term of this Agreement, by
      providing ISIS with written notice.

(f)   The party bearing primary responsibility for the prosecution,
      maintenance and defense of any Research Target Patent Rights
      pursuant to Article 8 herein will provide the other party hereto
      with a semiannual report summarizing the status of Research Target
      Patent Rights subject to a License to Exploit hereunder for which
      such party is responsible and will include updates to any Exhibits
      listing rights in any Patents licensed hereunder that are affected,
      if appropriate.

4.3   SUBLICENSES UNDER ISIS PATENT RIGHTS AND THIRD PARTY PATENT RIGHTS.

(a)   Any sublicense granted by ATL and its Affiliates under this
      Agreement is subject to and will be consistent with the terms and
      conditions of this Agreement and with the terms of the agreements
      pursuant to which ISIS obtained its rights in Third Party Patent
      Rights.  The grant of any such sublicense hereunder will not relieve
      ATL or its Affiliates of its obligations under this Agreement. ATL
      will promptly provide ISIS with copies of all sublicenses granted by
      ATL or its Affiliates, as well as Sublicensee contact information.

(b)   Subject to the terms and conditions of this Agreement and during the
      License Term, ATL and its Affiliates will have the right to grant
      sublicenses (each an "ATL Sublicense") under the licenses from ISIS set
      forth in Sections 4.1 and 4.2 to Third Parties as follows.

      (i)   ATL and its Affiliates may grant an ATL Sublicense to a Third
            Party collaborator under the Research Target Patent Rights solely
            for the purpose of enabling such Third Party to collaborate with ATL
            on bona fide research, development and commercialization work on a
            Research Target Compound and, after such collaborative work, to
            make, have made, use, offer for sale and sell a Product containing
            such Research Target Compound.

      (ii)  ATL and its Affiliates may grant an ATL Sublicense to a Third Party
            collaborator

                                       14



            under the ISIS Core Technology Patent Rights, the ISIS
            Formulation Patent Rights, the Manufacturing Patent Rights, the
            Research Target Patent Rights and the Third Party Patent Rights
            solely for the purpose of making, developing or using a
            Collaboration Compound or making, having made, using, developing,
            offering for sale or selling a Collaboration Compound Product.

      (iii) In the event of a material default by any Sublicensee under an ATL
            Sublicense, ATL will inform ISIS and take commercially reasonable
            efforts to cause the Sublicensee to cure the default or will
            terminate the ATL Sublicense. ATL will specifically state that ISIS
            is a third party beneficiary in any ATL Sublicense(s) hereunder.


4.4   MAXIMUM NUMBER OF LICENSES.

Not more than [***] Licenses to Research or Licenses to Exploit may be in
existence at any time during the term of this Agreement. Each such license is to
a discrete Research Target.

4.5   RIGHT OF FIRST REFUSAL.

(a)   During the term of this Agreement, if ATL is approached by a Third
      Party regarding, or elects to offer to a Third Party, the
      opportunity to collaborate on the development of a compound that
      modulates a Research Target other than IGF-1R, ATL will provide
      written notice of same to ISIS.  Such notice will include
      information identical to that presented by ATL to a Third Party
      including, at a minimum, (i) information possessed and disclosable
      by ATL that supports the development of such a compound and is
      reasonably necessary for ISIS to assess the commercial potential of
      such compound; and (ii) a proposal that ATL would be prepared to
      accept.  Within [***] days of receipt of such notice, ISIS will
      provide written notice to ATL indicating whether it is interested in
      negotiating with ATL to obtain the rights to develop and
      commercialize such compound with ATL.

(b)   If ISIS fails to respond to ATL's notification within [***] days or
      indicates that it is not interested in developing and commercializing such
      compound with ATL, ATL will thereafter be free to enter into discussions
      with one or more Third Parties regarding the development and
      commercialization of such compound.

(c)   If ISIS timely indicates its interest in obtaining such rights to
      develop and commercialize such compound with ATL, the parties will
      negotiate in good faith the terms of a separate development and
      commercialization agreement, which terms will be commercially
      reasonable, including without limitation license fees, milestone
      payments, and royalties, during the period up to [***] days
      following receipt of ISIS' notice.  If the parties are unable to
      execute such an agreement within such time period, despite good
      faith negotiations by each party, ATL will thereafter be free to
      develop and commercialize such compound with one or more Third
      Parties, provided that the terms offered to such Third Party include
      financial terms that are no more favorable than those offered to
      ISIS.

4.6   RIGHTS RETAINED BY ISIS.

                                       15



ISIS will retain the right to practice under all patent rights licensed to ATL
hereunder as necessary to carry out ISIS' obligations under this Agreement and
the Clinical Supply Agreement, and for any purpose other than to make, have
made, use, import, offer for sale and sell Collaboration Compound Products,
except as provided otherwise herein. ATL will not practice any of the patent
rights licensed to ATL hereunder other than as expressly licensed in this
Article 4.

4.7   ACCESS TO ADDITIONAL TECHNOLOGY.

(a)   If, after the Effective Date and during the Collaboration Term, ISIS
      comes to own, or acquires a license with the right to grant
      sublicenses thereunder, any new or additional ISIS Core Technology
      Patent Rights or Manufacturing Patent Rights, and ATL desires access
      to such rights, any licenses or sublicenses from ISIS to ATL under
      such Patents pursuant to Sections 4.1 and 4.2 are conditioned on
      ATL's agreement (i) to pay, on a flow-through basis, any royalties,
      milestones or other financial obligations owed to ISIS' licensor
      arising from a license or sublicense grant to ATL and the practice
      under such license or sublicense by ATL, its Affiliates or
      Sublicensees; and (ii) to abide by all terms of the agreement under
      which a Third Party license is granted to ISIS.

(b)   If, after the Effective Date and during the Collaboration Term, a
      change in the manufacturing process as a result of a change in the
      master batch records for ISIS 107248 requires access of ATL to
      Manufacturing Patent Rights that were not practiced in the
      manufacture of the ISIS 107248 API prior to such change, and if ISIS
      has obtained ownership or control of such Manufacturing Patent
      Rights by way of a license from or via collaboration with a Third
      Party, then any license or sublicense granted to ATL under such
      Manufacturing Patent Rights is conditioned on the prior agreement to
      be negotiated in good faith by the parties regarding (i) the
      assumption by ATL of all financial obligations owed to such Third
      Party arising from the grant of a license or sublicense to ATL and
      the practice under such license or sublicense by ATL, its Affiliates
      or Sublicensees; (ii) the payment to ISIS of an equitable portion of
      acquisition costs incurred by ISIS; and (iii) an agreement by ATL to
      abide by all terms of the agreement under which such Manufacturing
      Patent Rights were acquired, if applicable.

4.8   EFFECT OF TERMINATION OF LICENSES TO RESEARCH AND LICENSES TO
      EXPLOIT.

(a)   Upon termination of any License to Research or License to Exploit
      hereunder, ATL will assign and transfer to ISIS, to the extent ATL is not
      prohibited from doing so, all rights it owns or controls and any data and
      information relating to any Collaboration Compound or Collaboration
      Compound Product relating to the relevant Research Target obtained or
      generated by ATL during the term of the Agreement. [***].

(b)   If a License to Research or License to Exploit pertaining to a
      Research Target other than ISIS 107248 is terminated for any reason,
      promptly upon any such termination, the parties will

                                       16



      prepare a transition plan to ensure the seamless transition of any
      clinical studies and distribution and sales activities relating to any
      Antisense Inhibitor, Collaboration Compound, and/or Collaboration
      Compound Product from ATL to ISIS.  In addition, ATL will provide
      ISIS with any and all data relating to such Antisense Inhibitor,
      Collaboration Compound, Product using ISIS Standard Chemistry and/or
      to any ISIS Patent Rights relating to any Research Target that are
      in ATL's possession or control.

(c)   Upon termination of the License to Research or License to Exploit
      applicable to ISIS 107248, ATL will promptly return to ISIS all
      information and materials relating to ISIS 107248 provided to ATL by ISIS

      applicable to a Collaboration Compound or Collaboration Compound
      Product, ATL will promptly return to ISIS all quantities of API
      provided by ISIS under the Clinical Supply Agreement that have not
      been used.  In addition, ATL will promptly provide to ISIS all
      information and materials relating to such Collaboration Compound or
      Collaboration Compound Product provided to ATL by ISIS.  ATL will
      also promptly provide to ISIS all information and materials relating
      to such Collaboration Compound or Collaboration Compound Product
      independently generated by ATL, its Affiliates, Sublicensees or
      contractors.  With respect to information and materials relating to
      such Collaboration Compound or Collaboration Compound Product that
      were independently generated by ATL, its Affiliates, Sublicensees or
      contractors, ISIS will compensate ATL as follows:

(d)   Except as otherwise provided above, the minimum royalty payable to ISIS by
      ATL for sales of any Product by ATL or its Affiliates for which ISIS has
      established efficacy in an animal model or has conducted preclinical
      toxicity studies will be negotiated in good faith by the parties on a
      case-by-case basis, but will not be less than [***] of Net Sales.

(e)   For Products under (a) or (c), in addition to any minimum royalties
      due under (a) or (c), the royalty payable to ISIS by ATL for sales
      of any Product by ATL or its Affiliates, the manufacture, use, sale,

5.5   EXAMPLES.

                                       19



(a)   EXAMPLE OF CALCULATION OF ROYALTY RATE FOR SALES OF PRODUCTS COMPRISING
      ISIS 107248 BY ATL OR ITS AFFILIATES:

      The royalty payable to ISIS for sales of Product by ATL or its Affiliates
      (as a percentage of Net Sales) comprising non-topically-administered
      formulations of ISIS 107248 is calculated as follows (assuming all
      relevant patent rights are issued and unexpired):


[***]


(b)   EXAMPLE OF ROYALTIES AND SUBLICENSE INCOME PAYABLE TO ISIS BY ATL OR ITS
      AFFILIATES ON SALES OF PRODUCTS COMPRISING ISIS 107248 BY SUBLICENSEES:

      [***]

5.6   PAYMENT OF ROYALTIES AND INCOME; REPORTS.

ATL will make royalty payments to ISIS for each Product sold during a Calendar
Quarter within [***] days of the last day of that Calendar Quarter. Each royalty
payment will be accompanied by a written report for that Calendar Quarter
showing the calculation of Net Sales of the Product sold by ATL, its Affiliates
and its Sublicensees worldwide during the quarterly reporting period and the
calculation of the royalties and Sublicense Income payable under this Agreement,
all on a country-by-country and Product-by-Product basis.

5.7   PAYMENT MODALITIES; FOREIGN CURRENCY CONVERSION; LATE PAYMENT
      CHARGES.

(a)   PAYMENTS. All payments to ISIS under this Agreement will be made in United
      States Dollars by bank wire transfer in next day available funds to such
      bank account in the United States designated in writing by ISIS from time
      to time. All amounts payable to ISIS hereunder are noncreditable and
      nonrefundable.

(b)   LATE PAYMENTS; COLLECTIONS.   In the event that any payment,
      including royalty, milestone or research payments, due hereunder is
      not made when due, the payment will bear interest from the date due
      at the lesser of (i) [***] per month, compounded monthly, or (ii)
      the highest rate permitted by law; provided, however, that in no
      event will such rate exceed the maximum legal annual interest rate.
      If ATL disputes the amount of an invoice presented by ISIS within
      [***] days of receipt of such invoice, the late fees will only apply
      to the correct amount as later determined or agreed. The payment of
      such interest will not limit a party from exercising any other
      rights it may have as a consequence of the lateness of any payment.
      In addition, ATL agrees to pay all costs of collection, including
      reasonable attorneys' fees, incurred by ISIS in enforcing the
      payment obligations of ATL after a due date has passed under this
      Agreement.


5.8   AUDITS REQUESTED BY ISIS.


                                       20





(a)   Upon the written request of ISIS, and not more than once in each
      calendar year, ATL will permit ISIS' independent certified public
      accountant to have access during normal business hours to such of
      the records of ATL as may be reasonably necessary to verify the
      accuracy of the royalty reports hereunder for the current year and
      the preceding 2 years prior to the date of such request.  The
      accounting firm will disclose to ISIS only whether the royalty
      reports are correct or incorrect, the specific details concerning
      any discrepancies, and the corrected amount of Net Sales and
      Sublicense Income.  No other information will be provided to ISIS.

(b)   At the request of ISIS, ATL will direct its Affiliates to permit
      audits of the Affiliates' records in accordance with the provisions
      of subsection (a) above.  Further, ATL will include in each
      sublicense granted by it pursuant to this Agreement a provision
      requiring the Sublicensee to submit reports to ATL, to keep and
      maintain records of sales made pursuant to such sublicense and to
      grant access to such records by ISIS' independent accounting firm,
      to the same extent required of ATL hereunder. ISIS' independent
      accounting firm will also be granted access to such reports in ATL's
      possession as part of the audit referenced in subsection (a) above.

(c)   If such accounting firm concludes that additional royalties were
      owed during such period, ATL will pay the additional royalties
      within [***] days of the date ISIS delivers to ATL such accounting
      firm's written report.  The fees charged by such accounting firm
      will be paid by ISIS unless the additional royalties, milestones or
      other payments owed by ATL exceed [***] of the royalties, milestones
      or other payments paid for the time period subject to the audit, in
      which case ATL will pay the reasonable fees and expenses charged by
      the accounting firm.

(d)   ISIS will treat all financial information subject to review under this
      Section 5.8 or under any sublicense agreement in accordance with the
      confidentiality provisions of Article 9, and will cause its accounting
      firm to enter into an acceptable confidentiality agreement with ATL and
      its Sublicensees obligating such firm to retain all such financial
      information in confidence pursuant to such confidentiality agreement.

5.9   AUDITS REQUESTED BY ATL.

(a)   Upon the written request of ATL, and not more than once in each
      calendar year, ISIS will permit ATL's independent certified public
      accountant to have access during normal business hours to such of
      the records of ISIS as may be reasonably necessary to verify the
      accuracy of the invoices submitted to ATL hereunder for the 12
      months preceding the date of such request.  The accounting firm will
      disclose to ATL only whether the invoiced amounts are correct or
      incorrect, the specific details concerning the basis for the
      invoiced amounts, and the corrected amount, if applicable. No other
      information will be provided to ATL.


                                      21


(b)   If such accounting firm concludes that any amounts invoiced were in
      error during such period and ATL is entitled to a refund of such
      amounts, ISIS will refund to ATL the amounts overcharged within
      [***] days of the date ATL delivers to ISIS such accounting firm's
      written report.  The fees charged by such accounting firm will be
      paid by ATL unless the additional refunded amounts owed by ISIS
      exceed [***] of the total amount for which ATL was invoiced during
      the time period subject to the audit, in which case ISIS will pay
      the reasonable fees and expenses charged by the accounting firm.

(c)   ATL will treat all financial information subject to review under this
      Section 5.9 in accordance with the confidentiality provisions of Article 9
      and will cause its accounting firm to enter into an acceptable
      confidentiality agreement with ISIS obligating such firm to retain all
      such financial information in confidence pursuant to such confidentiality
      agreement.


5.10  TAXES.

If laws, rules or regulations require withholding of income taxes or other
taxes imposed upon payments set forth in this Article 5, ATL will make such
withholding payments as required and subtract such withholding payments from
the payments set forth in this Article 5. ATL will submit appropriate proof
of payment of the withholding taxes to ISIS within a reasonable period of
time.

                                    ARTICLE 6

                   USE OF MATERIALS, DATA AND INFORMATION

      in furtherance of a Development Program or Collaborative Research Program,
      will not be used or delivered to or for the benefit of any Third Party
      without the prior written consent of ISIS, and will not be used in
      research or testing involving human subjects. The Antisense Inhibitors and
      any related research materials supplied under this Agreement must be used
      with prudence and appropriate caution in any experimental work, since not
      all of their characteristics may be known. ATL agrees to comply with all
      applicable laws, rules and regulations in connection with its use of
      Antisense Inhibitors and related research materials provided hereunder.

6.2   All Antisense Inhibitors and related research materials provided to ATL
      hereunder are proprietary to ISIS. Any unused quantities of Antisense
      Inhibitors and research materials will be returned to ISIS by ATL, upon
      ISIS' request, at ISIS' expense.

6.3   ATL may use data and information generated pursuant to a Gene Walk or
      GeneTrove Investigation, or otherwise provided to ATL by ISIS hereunder,
      for internal drug discovery purposes only, consistent with the terms of
      this Agreement. Except as provided otherwise herein, all data and
      information provided to ATL by ISIS pursuant to this


                                      22


      Agreement is confidential and proprietary to ISIS and will not be
      disclosed to Third Parties, consistent with the provisions of Article 9
      herein. ISIS acknowledges that ATL may wish to provide such data and/or
      information to a Third Party in connection with ATL's bona fide
      development, commercialization or partnering activities under this
      Agreement; ISIS will not unreasonably withhold its consent to such a
      transfer of data and information, provided that the receiving party is
      advised of the confidentiality provisions hereunder and agrees to be bound
      thereby. Notwithstanding the foregoing, ISIS reserves the absolute right
      to withhold consent if ATL wishes to transfer such data or information to
      an antisense company or other competitor of ISIS.

6.4   Consistent with the foregoing provisions, if ATL conducts studies
      comparing ISIS Standard Chemistry with the chemistry of a Third Party, all
      data and information incorporating or relating to ISIS Standard Chemistry
      that result from such studies is confidential and proprietary to ISIS and
      will not be disclosed to Third Parties, consistent with the provisions of
      Article 9 herein.

                                    ARTICLE 8

                              INTELLECTUAL PROPERTY

8.1   OWNERSHIP OF INVENTIONS.

(a)   Neither party hereto will be deemed by this Agreement to have been granted
      any license or other rights to the other party's rights in any inventions,
      technology, discoveries, or other proprietary property (collectively,
      "Inventions") existing as of the Effective Date of this Agreement, except
      as expressly provided herein.

(b)   Except as provided otherwise herein, each party will solely own all
      Inventions that are made (as determined by U.S. rules of
      inventorship) solely by employees of or Consultants to that party
      pursuant to the Collaborative Research Program or any Development
      Program under this Agreement.  Such an Invention will be an "ISIS
      Invention" or an "ATL Invention," as the case may be, and Patents
      claiming such Inventions will be "ISIS Patents" or "ATL Patents,"
      respectively.

(c)   ISIS agrees to assign to ATL its rights in any ISIS Inventions or
      Joint Inventions claiming Antisense Inhibitors that modulate IGF-1R
      and methods of using same, provided that a License to Research or
      License to Exploit for IGF-1R exists.  If ATL does not convert the
      License to Research for IGF-1R into a License to Exploit IGF-1R, or
      if the License to Research or License to Exploit applicable to
      IGF-1R is terminated for any reason, ATL will assign back to ISIS
      the latter's rights in any such ISIS Inventions and Joint
      Inventions, as well as ISIS' rights in any Patents filed on such
      Inventions.  Notwithstanding the foregoing, if such assignment of
      rights back to ISIS would interfere with ATL's ability to practice
      any ATL Inventions or ATL Patent Rights pertaining to IGF-1R, ISIS
      agrees to sublicense, in favor of ATL, only that portion of any such
      Invention or Patent, and only for that time period, as is required
      for ATL to practice an ATL Invention or ATL Patent that would
      otherwise infringe the ISIS Invention or ISIS Patent, on a
      nonexclusive, mutually agreeable basis that is consistent with the
      royalties set out in this Agreement, provided that ISIS is not
      otherwise precluded from doing so.

(d)   Except as provided otherwise herein, ISIS and ATL will jointly hold
      title to all Inventions, whether or not patentable, that are made
      (as determined by the U.S. rules of inventorship) jointly by
      employees of or Consultants to ISIS and ATL pursuant to the
      Collaborative


                                      24


      Research Program or any Development Program under this Agreement,
      as well as to Patents filed thereon.  Such Inventions will be "Joint
      Inventions," and Patents claiming such Joint Inventions will be "Joint
      Patents."  ISIS and ATL will promptly provide each other with notice
      whenever a Joint Invention is made. The parties agree and acknowledge
      that, except insofar as this Agreement provides otherwise, the default
      rights conferred on joint owners under US patent law, including the right
      of each party to independently practice, license and use a Joint Patent,
      will apply in relation to the Joint Patents throughout the world as though
      US patent law applied worldwide.

(e)   The parties understand that if ATL or a Third Party collaborator of ATL
      provides a proprietary gene sequence or utility not known to ISIS, the
      discovery of inhibitors of that sequence may be a Joint Invention.
      Similarly, the parties understand that the discovery of a method of
      treating human disease by inhibiting a particular gene product, where
      ISIS' Antisense Inhibitor data is used to support the claims of the
      Patent, may be a Joint Invention.

(f)   The parties agree, upon reasonable request, to execute any documents
      reasonably necessary to effect and perfect each other's ownership of any
      Invention.

(g)   [***].


8.2   FILING, PROSECUTION, MAINTENANCE, ENFORCEMENT AND DEFENSE OF PATENTS
      OWNED OR CONTROLLED BY ISIS AND OF CERTAIN JOINT PATENTS.

(a)   Except as provided otherwise herein, ISIS will have the sole and
      exclusive right to file, prosecute, maintain, enforce and defend any
      Research Target Patent Rights and any ISIS Patents or Joint Patents
      filed on Inventions claiming an Antisense Inhibitor to a Research
      Target or a method of treatment using an antisense molecule that
      modulates a Research Target subject to a License to Research or
      License to Exploit hereunder, regardless of inventorship.  ISIS will
      consider ATL's input with respect to the prosecution, maintenance,
      enforcement and defense of any such Patents.  ISIS will also
      consider any supporting information provided by ATL that relates to
      the Research Target and its uses, as well as any supporting IN VIVO
      or IN VITRO efficacy data generated from experiments performed by
      ATL or its collaborators.  As used herein, Patent prosecution
      includes, without limitation, the handling of interference
      proceedings, oppositions, reexaminations and reissues.

(b)   In the event ATL proposes the filing of a Joint Patent pursuant to
      subsection (a) and ISIS does not wish to file and prosecute such Joint
      Patent, ATL will have the right to file, prosecute, maintain, enforce and
      defend such Joint Patent. ATL will consider ISIS' input with respect to
      the prosecution, maintenance, enforcement and defense of any such Joint
      Patents.

(c)   ISIS will also have the sole and exclusive right, in its sole discretion,
      to file, prosecute, maintain, enforce and defend any Patents within the
      ISIS Core Technology Patent Rights, the Manufacturing Patent Rights, and
      the ISIS Formulation Patent Rights.


                                      25


(d)   ISIS will pay for its own labor costs incurred in the filing, prosecution,
      maintenance, enforcement and defense of any Patents for which ISIS is
      responsible hereunder.

(e)   ATL will reimburse ISIS for reasonable materials and out of pocket
      expenses incurred in connection with the activities recited in subsections
      (a), (c) and (d). As used herein, materials and out-of-pocket expenses
      means costs, other than ISIS' labor costs, [***]. ISIS will invoice ATL on
      a quarterly basis and ATL will submit payment to ISIS consistent with the
      provisions of Article 7 herein.

(f)   Should ATL elect not to pay expenses relating to Patent protection
      in a particular country, ATL will provide ISIS with written notice
      of same, and ATL's payment obligations with respect to that country
      will cease once ISIS has received such notice, provided that all
      noncancelable costs and expenses incurred by ISIS prior to such date
      will nevertheless be reimbursed by ATL.  Immediately upon ISIS'
      receipt of such written notice from ATL, the applicable License to
      Research or License to Exploit will be terminated with respect to
      such country.

(g)   With respect to any ISIS Patent Rights exclusively licensed to ATL under a
      License to Exploit, ISIS will promptly advise ATL if ISIS becomes aware of
      any suspected or actual infringement of such ISIS Patent Rights by any
      person. Similarly, ATL will promptly advise ISIS if ATL becomes aware of
      any suspected or actual infringement of such ISIS Patent Rights by any
      person.

(h)   If ISIS fails to initiate proceedings against any actual or suspected
      infringement of the ISIS Patent Rights exclusively licensed to ATL
      hereunder or to defend any claim of infringement against the parties
      pertaining to such rights within [***] days of receipt of a notice from
      ATL asking ISIS to do so, ATL will be entitled to initiate those
      proceedings at ATL's expense.

(i)   Except as provided otherwise herein, ISIS will endeavor to take all action
      necessary to ensure that the ISIS Patent Rights that are or become subject
      to a License to Research or License to Exploit are maintained and
      diligently prosecuted.

8.3   FILING, PROSECUTION, MAINTENANCE, ENFORCEMENT AND DEFENSE OF PATENTS
      OWNED OR CONTROLLED BY ATL.

(a)   Except as provided otherwise herein, ATL will have the sole and
      exclusive right and responsibility, in its sole discretion, to file,
      prosecute, maintain, enforce and defend any Patents filed on
      Inventions made solely by ATL (i.e., ATL Patents).  ATL will provide
      ISIS with a semiannual report summarizing the status of any such ATL
      Patents. ATL hereby grants ISIS a worldwide, royalty-free,
      sublicensable, perpetual, nonexclusive license to practice under
      ATL's rights to any such ATL Patent to carry out the activities
      contemplated by this Agreement and to make, have made, use, import,
      offer for sale and sell products other than a Product.


                                      26


(b)   If a License to Exploit is granted to ATL with respect to a Research
      Target or Collaboration Compound hereunder, ISIS will promptly
      thereafter transfer to ATL the sole and exclusive right to
      prosecute, maintain, enforce and defend any Patents owned,
      controlled or to which ISIS has prosecution rights that are within
      the Research Target Patent Rights.  ATL will consider ISIS' input
      with respect to the prosecution, maintenance, enforcement and
      defense of any such Patents.  If ATL decides to discontinue the
      prosecution, maintenance, enforcement or defense of any such Patent
      entirely or in a particular country, it will inform ISIS thereof
      with sufficient time for ISIS to assume those responsibilities with
      respect to such Patent and will thereafter transfer the relevant
      Patent files to ISIS or its designee.

8.4   INFRINGEMENT OF THIRD PARTY PATENTS.

If either party receives notice that a Product infringes a Third Party Patent,
and the parties hereto agree to settle with and pay royalties to such Third
Party, the additional royalty burden will be allocated as follows.

(a)   If the alleged infringement is due to ATL's practice of ISIS Core
      Technology Patent Rights, Manufacturing Patent Rights, or ISIS 107248
      Patent Rights, [***].

(b)   If the alleged infringement is due to ATL's practice of any other
      Patent Rights licensed hereunder, [***].

8.5   PATENT COORDINATORS.

(a)   Within 30 days of the Effective Date, the parties will each select a
      Patent Coordinator ("PC") to facilitate and coordinate the preparation,
      filing, prosecution and maintenance of Patents pursuant to this Agreement.
      The parties may agree to name additional Patent Coordinators, as long as
      equal representation is maintained.

(b)   During the Collaboration Term, the PCs will be the primary contacts for
      interaction between the parties with respect to the activities referenced
      in (a).

(c)   The PCs will meet as needed during the Collaboration Term. Meetings will
      be via teleconference or videoconference, or as the parties may otherwise
      agree. The frequency, dates and times of all meetings will be mutually
      agreed upon by the parties. At their first meeting, the PCs will determine
      such procedures as they will reasonably require to conduct their
      activities.

(d)   The parties further agree that to facilitate the activities
      described in this Section, ATL's Patent Coordinator may, upon prior
      written notice to ISIS' Patent Coordinator and at such times as are
      mutually agreed upon by the Patent Coordinators, obtain access to
      and make copies of Patent file documents that are relevant to
      filing, prosecution, maintenance, enforcement and defense of Patents
      licensed to ATL hereunder.   Any and all such documents will be
      maintained by ATL in confidence, pursuant to the provisions of
      Article 9 below.


                                      27


                                    ARTICLE 9

      condition that such Affiliates and Third Parties agree to be bound
      by the confidentiality obligations contained in this Agreement,
      provided the term of confidentiality for such Affiliates and Third
      Parties will be no less than 7 years; or

(c)   if such disclosure is required by law or court order, provided that notice
      is promptly delivered to the other party in order to provide an
      opportunity to challenge or limit the disclosure obligations.

      this Agreement.

(b)   Except as otherwise provided herein or required by law, neither
      party will originate any publication, news release or other public
      announcement, written or oral, whether in the public press, or

11.1    INDEMNIFICATION BY ATL.

ATL will indemnify, defend and hold ISIS and its agents, employees, officers and
directors (the "ISIS Indemnitees") harmless from and against any and all
liability, damage, loss, cost or


                                     29



expense (including reasonable attorneys' fees) arising out of Third Party
claims or suits related to (a) ATL's performance of its obligations under
this Agreement; (b) breach by ATL of its representations and warranties set

pursuant to this Section 11.1 will not apply to the extent such claims or
suits result from the gross negligence or willful misconduct of any of the
ISIS Indemnitees. Notwithstanding the foregoing, ATL will have no obligation
to indemnify the ISIS Indemnitees with respect to claims arising out of
breach by ISIS of its representations and warranties set forth in Section
13.1.

11.2    INDEMNIFICATION BY ISIS.

ISIS will indemnify, defend and hold ATL and its Affiliates and each of their
respective agents, employees, officers and directors (the "ATL Indemnitees")
harmless from and against any and all liability, damage, loss, cost or
expense (including reasonable attorney's fees) arising out of Third Party
claims or suits related to (a) ISIS' performance of its obligations under
this Agreement; or (b) breach by ISIS of its representations and warranties

hereto, (ii) cooperate with the indemnifying party in the defense of such
claim or suit, and (iii) permit the indemnifying party to control the defense
of such claim or suit, including without limitation the right to select
defense counsel. In no event, however, may the indemnifying party compromise
or settle any claim or suit in a manner which admits fault or negligence on
the part of the indemnified party without the prior written consent of the
indemnified party. The indemnifying party will have no liability under this
Article 11 with respect to claims or suits settled or compromised without its
prior written consent.

                                   ARTICLE 12

                        TERM AND TERMINATION OF AGREEMENT

12.2  TERMINATION UPON FUNDAMENTAL BREACH.

This Agreement may be terminated upon written notice by either party to the
other at any time during the term of this Agreement if the other party is in
fundamental breach of its obligations hereunder (i.e., a breach which goes to
the heart of the Agreement) and has not cured such breach within 90 days
after written notice requesting cure of the breach; providing, however, that
in the event of a good faith dispute with respect to the existence of such a
fundamental breach, the 90-day cure period will be stayed until such time as
the dispute is resolved pursuant to Section 16.6 hereof. Material breaches
that are not fundamental give rise solely to a right of damages but not a
right to terminate the Agreement.

12.3  TERMINATION UPON BANKRUPTCY; RIGHTS IN BANKRUPTCY.

All rights and licenses granted under or pursuant to this Agreement by ISIS
or ATL are, and will otherwise be deemed to be, for purposes of Section
365(n) of the U.S. Bankruptcy Code, licenses of right to "intellectual
property" as defined under Section 101 of the U.S. Bankruptcy Code. The
parties agree that the parties, as licensees of such rights under this
Agreement, will retain and may fully exercise all of their rights and
elections under the U.S. Bankruptcy Code. The parties further agree that, in
the event of the commencement of a bankruptcy proceeding-by or against either
party under the U.S. Bankruptcy Code, the party hereto which is not a party
to such proceeding will be entitled to a complete duplicate of (or complete
access to, as appropriate) any such intellectual property and all embodiments
of such intellectual property, and same, if not already in their possession,
will be promptly delivered to them (i) upon any such commencement of a
bankruptcy proceeding upon their written request therefor, unless the party
subject to such proceeding elects to continue to perform all of its
obligations under this Agreement, or (ii) if not delivered under (i) above,
following the rejection of this Agreement by or on behalf of the party
subject to such proceeding upon written request therefor by the non-subject
party.

12.4  ACCRUED RIGHTS AND SURVIVING OBLIGATIONS.

Expiration or termination of the Agreement will not relieve the parties of
any obligation accruing prior to such expiration or termination. Sections
4.8, 12.4 and 16.7, and Articles 5-9, 11 and 13-15 will survive expiration or
termination of the Agreement. Provisions concerning reporting requirements
will continue in effect in accordance with any applicable timetables set
forth herein. Any expiration or early termination of this Agreement will be
without prejudice to the rights of either party against the other accrued or
accruing under this Agreement prior to termination, including the obligation
to pay royalties for Product sold prior to such termination.

      compliance.  Each party will promptly notify the other party of any
      relevant new instructions or specifications required by a Regulatory
      Authority, and of other applicable and regulations of which that
      party becomes aware.  The parties will confer with each other with
      respect to the best means to comply with


                                       4


      such requirement and will allocate any costs of implementing such
      changes on an equitable basis.

(b)   ISIS will perform quality control testing as is specified (i) in the API
      Specification; and (ii) as required by a Regulatory Authority and by the
      mutual written consent of the parties, on each lot of API supplied for use
      in Product, prior to shipment of such API.

(c)   As ATL develops Collaboration Compounds pursuant to the Collaboration and
      License Agreement, modified or expanded API Specifications appropriate to
      the stage of development may be required. Such API Specifications will be
      consistent with the API Specifications of other ISIS antisense compounds
      at a similar stage of development.

(d)   New API Specifications will be prepared and processed as follows.

      (i)   Not later than [***] days prior to its submission of an API order
            estimate for a new Collaboration Compound to ISIS, ATL will provide
            ISIS with written notice of its intent to order API for which API
            Specifications have not yet been prepared.

      (ii)  Upon receipt of such written notice, ISIS will initiate any required
            development work and subsequently prepare an API Specification for
            each new Collaboration Compound that ATL intends to order, which
            will be consistent with the API Specifications of other ISIS
            antisense compounds at a similar stage of development.

      (iii) Once a new API Specification has been prepared by ISIS, it will be

(b)   In the event of a loss of work in process or API prior to the transfer of
      title pursuant to the Delivery of API as provided in subsection (a) above,
      any uninsured portion of the loss will be shared by ATL and ISIS as
      follows: [***]. Any deductible will be applied ratably against all items
      damaged or lost.

5.3   ACCEPTANCE AND CLAIMS; MATERIALS REVIEW BOARD

(a)   If ATL claims that any sample of API did not meet the warranty specified
      in Section 10.1, ATL will notify ISIS in writing within 30 days of such
      Delivery, and a joint Materials Review Board formed under subsection (b)
      below will review the test data generated by ATL and ISIS under QA
      approved procedures mutually agreed upon by the parties within 30 days
      after ATL's notice to ISIS.

(b)   Promptly after the Effective Date, ISIS and ATL will each select 2 members
      of their in-house materials review boards (or other senior personnel or
      Contractors with appropriate qualifications) to participate in a joint
      Materials Review Board ("MRB") that will review and consider any test data
      generated by ATL and ISIS with respect to the Delivered lot of API.

(c)   If the members of the MRB are thereafter unable to agree as to
      whether the API met the warranty specified in Section 10.1, the
      parties will cooperate and have the test data reviewed by an
      independent third party selected by ATL and approved by ISIS, which
      approval will not be unreasonably withheld.  If the independent
      third party reviewer cannot determine whether the Delivered API in
      dispute met the warranty of Section 10.1, a sample of the batch of
      the Delivered API in dispute retained by ISIS will be analyzed in
      accordance with the API Specifications, under QA approved
      procedures, by an independent testing laboratory of recognized
      repute selected by ATL and approved by ISIS, which approval will not
      be unreasonably withheld.  Unless provided otherwise herein, the
      results of such laboratory testing will be final and binding on the
      parties on the issue of compliance of the API with such warranty.

(d)   If the API is determined to meet the warranty set forth in Section
      10.1, ATL will bear the cost of any third party review and/or
      independent laboratory testing performed pursuant to subsection (c)
      above and will pay for the API in accordance with the terms of this
      Agreement.  If the API is determined not to meet the warranty set
      forth in Section 10.1, ISIS will bear the cost of any third party
      review and/or independent laboratory testing performed pursuant to
      subsection (c) above.

(e)   If ISIS agrees, or if it is determined pursuant to subsection (c)
      above, that API did not conform to the warranty set forth in Section
      10.1, ISIS will use commercially reasonable efforts to Manufacture
      and Deliver a replacement batch of API to ATL for the batch of


                                       7


      API that did not conform to such warranty, and ATL will pay ISIS for any
      such replacement batch of API, including without limitation, all
      costs and expenses associated with such Manufacture, consistent with
      the provisions of Section 5.1 herein.  The API Supply Cost for the
      Manufacture of the batch of API that did not conform to such
      warranty will be shared by ATL and ISIS as follows: ISIS will be
      responsible for the [***] for such batch of API; and ATL will be
      responsible for the [***] for such batch of API.  Replacement of API
      will be ATL's sole and exclusive remedy for breach of the warranty
      set forth in Section 10.1.

(f)   Any Delivered API which ISIS agrees did not meet, or which was determined
      not to have met, the Section 10.1 warranty that is in ATL's control will,
      at ISIS' option, either be returned to ISIS or will be destroyed pursuant
      to ISIS' instructions and with ATL's approval, which approval will not be
      unreasonably withheld, at ISIS' expense.

(g)   Failure by ATL to notify ISIS within [***] after Delivery of API which
      does not meet the warranty under Section 10.1 will be a waiver of the
      remedies available to ATL under this Section 5.3.

(h)   Should either party identify any possible latent defect of API that is not
      revealed by the procedures set forth above within [***] of receipt of any
      shipment by ATL, it will so notify the other party immediately upon
      discovery. ATL and ISIS will discuss in good faith and agree upon the
      appropriate measures to be taken by the parties related to such latent
      defect.

5.4   TERMS OF SALE

      The terms and conditions of this Agreement will be controlling over any
      inconsistent terms or conditions included in any agreed-upon order for API
      or any other sales acknowledgment or document. No provision of any ATL
      forms purporting to be orders for API that may impose different conditions
      than those herein referenced upon ISIS, ATL or their respective
      Contractors will be of any force or effect unless expressly agreed to in
      writing by both parties.

5.5   PAYMENT TERMS

(a)   PAYMENTS. All payments to ISIS under this Agreement will be made in United
      States Dollars by bank wire transfer in next day available funds to such
      bank account in the United States designated in writing by ISIS from time
      to time. All amounts payable to ISIS hereunder are noncreditable and
      nonrefundable, unless specifically provided otherwise herein.

(b)   LATE PAYMENTS; COLLECTIONS.   In the event that any payment,
      including royalty, milestone or research payments, due hereunder is
      not made when due, the payment will bear interest from the date due
      at the lesser of (i) [***] per month, compounded monthly, or (ii)
      the highest rate permitted by law; provided, however, that in no
      event will such rate exceed the maximum legal annual interest rate.
      The payment of such interest will not


                                       8



      limit a party from exercising any other rights it may have as a
      consequence of the lateness of any payment.  [***]

                               RECORDS AND AUDITS

8.1   QUALITY STANDARDS

      ISIS will keep complete, accurate and authentic accounts, notes, data and
      records of all of ISIS' work performed under this Agreement, including,
      but not limited to, complete and adequate records pertaining to the
      methods and facilities used for the Manufacture in accordance with master
      production records, batch production records, product history documents
      (e.g., master formulae, validation packages, specifications,
      batch-specific deviation reports, COAs) Standard Operating Procedures
      ("SOPs"), as well as the applicable regulations, including in the United
      States, so that API may be used in the production of a substance to be
      used in humans. ISIS will maintain these records for 2 years after
      expiration of the Product that incorporates the particular API. ATL will
      notify ISIS in writing of the expiration of Products that incorporate
      specific API and if ATL changes the expiration date on any Product. SOPs
      will be maintained for 5 years after the document is superseded or
      deleted. Upon expiration of the retaining periods for the respective
      records as provided in this Section and in case ISIS wishes to cease
      retention of such records, ISIS will notify ATL so that ATL may, at its
      cost, retain such records.

8.2   API SUPPLY PRICE; RECORD KEEPING AND AUDIT

(a)   ISIS will keep accurate records in sufficient detail to enable the
      API Supply Price to be verified. Upon written request of ATL and not
      more than once in each Calendar Year, ISIS will permit ATL's
      independent certified public accountant (or equivalent) to have

                                       12



      access during normal business hours to such records of ISIS as may
      be reasonably necessary to verify the accuracy of the invoices for
      API Supply Price submitted to ATL hereunder for the preceding
      Calendar Year. Once specific records have been audited under this
      Section 8.2, no further audit of such records may be made.  The
      accounting firm will disclose to ATL only whether the invoiced
      amounts are correct or incorrect, the specific details concerning
      the basis for the invoiced amounts, and the corrected amount, if
      applicable.  No other information will be provided to ATL.

(b)   If such accounting firm concludes that any amounts invoiced were in
      error during such period and ATL is entitled to a refund of such
      amounts, ISIS will refund to ATL the amounts overcharged within
      [***] days of the date ATL delivers to ISIS such accounting firm's
      written report.  The fees charged by such accounting firm will be
      paid by ATL unless the additional refunded amounts owed by ISIS
      exceed [***] of the total amount for which ATL was invoiced during
      the time period subject to the audit, in which case ISIS will pay
      the reasonable fees and expenses charged by the accounting firm.

(c)   ATL and its accounting firm will treat all financial information
      subject to review under this Section 8.2 in accordance with the
      confidentiality provisions of Article 9 of the Collaboration and
      License Agreement, which provisions are incorporated herein and made
      part of this Agreement by reference, and will cause its accounting
      firm to enter into an acceptable confidentiality agreement with ISIS
      obligating such firm to retain all such financial information in
      confidence pursuant to such confidentiality agreement.

8.3   TECHNOLOGY TRANSFER RECORDS

      ISIS will maintain records, in sufficient detail and in good scientific
      manner appropriate for patent, regulatory and manufacturing purposes,
      which will fully and properly reflect all of the work done and the
      progress achieved in the performance of the Release Technology Transfer

                                PRODUCT WARRANTY


10.1  API SPECIFICATIONS; CGMPS; APPLICABLE LAWS

      Subject to Section 10.2 below, ISIS warrants that the API will, at the
      time of Delivery, be Manufactured in accordance with and meet (a) the API
      Specification; (b) cGMP; and (c) the Legal Requirements.

10.2  FOREIGN MANUFACTURING REQUIREMENTS

      If the cGMP or the Legal Requirements applicable to the Manufacture of API
      for use in the U.S. (the "U.S. Manufacturing Requirements") are different

                                 QUALITY SYSTEMS


11.1  MATTERS RELATING TO THE FACILITY

(a)   ISIS will Manufacture API supplied by ISIS hereunder at the Facility,
      which ISIS represents and warrants has been and will be approved by
      Agencies which have inspected or will inspect the Facility for the
      manufacture of API. ISIS will perform release testing of API at the
      Facility and/or the facility of subcontractors approved by ISIS.

(b)   ISIS will arrange for one or more qualified technical specialists
      from ATL or one or more qualified Contractors of ATL approved by
      ISIS (which approval will not unreasonably be withheld), upon
      reasonable prior notice and during normal business hours, to conduct
      inspections of the Facility.  Observations and conclusions of ATL's
      audits or inspections will be issued to and promptly discussed with
      ISIS and such corrective action as ATL determines to be reasonably
      required will be promptly implemented by ISIS. ISIS will maintain
      complete and accurate records of all reasonably relevant information
      relating to the performance by ISIS of its obligations hereunder.
      ISIS will permit ATL or its ISIS-approved Contractors to review,
      during the inspection at the Facility, relevant cGMP documentation.
      The total number of inspections under this Section per CalendarYear
      will not exceed two.

11.2  TESTING

(a)    ISIS will perform, at its laboratories, such tests as are indicated
       in the API Specification. Such tests and methods will be qualified
       by ISIS and accepted by ATL prior to use and certain of such tests
       will be stability indicating. No production lot of API will be
       released for Delivery unless such tests show the API to meet the API
       Specification. Should any production lot fail to meet the API
       Specification, such lot will not be released, unless the failure is
       identified following release, in which case the identifying party
       will immediately notify the other party and they will cooperate on
       the actions to be taken.

(b)   ISIS is responsible for obtaining and retaining, at ATL's expense, the
      amount of API required for quality control release testing as indicated in
      the API Specification. Such amounts will be retained for a period of not
      less than one (1) year from the last retest date prescribed by ISIS, and
      thereafter shipped at ATL's request for longer term storage at a
      designated ATL facility.

(c)   After Technology Transfer with respect to analytical testing is
      complete in accordance with the terms contained herein and in the
      Collaboration and License Agreement, ATL may perform, at a
      designated quality control laboratory of recognized repute selected
      by ATL and approved by ISIS, which approval will not be unreasonably
      withheld, such quality control tests of API as specified in the API
      Specification and advise ISIS of any failure of such API to meet the
      API Specification.

                                       15



11.3  INFORMATION RELATING TO MANUFACTURING CONDITIONS

(a)   Each party will notify the other immediately of any health hazards with
      respect to API of which it becomes aware which may impact employees
      involved in the Manufacture or handling of API or Product.

(b)   Each party will promptly advise the other of any safety or toxicity
      problem that is not part of the knowledge base readily available in
      chemical manufacturing facilities of which either party becomes aware
      regarding the API or Product.

11.4  AGENCY INSPECTIONS

      ISIS hereby agrees to advise ATL of any visit or inspection by an Agency
      of the Facility relating to the Manufacture of API, provide copies of all
      communications relating thereto and will permit one or more qualified
      representative(s) of ATL to be present, when possible. If ATL is not
      present during such a visit or inspection for any reason, ISIS will
      promptly provide a copy of the actual report of the results of the
      inspection to ATL. ISIS will furnish ATL copies of all reports, documents
      or correspondence with respect to any such Agency inspections of the
      Facility.

11.5  STORAGE AND DELIVERY

      ISIS will store and Deliver API in accordance with the applicable API
      Specification and cGMP.

                               REGULATORY MATTERS


12.1  ISIS will prepare and promptly provide necessary and useful information,
      including without limitation Manufacturing information, as is needed to
      support filings of Registrations by ATL, its Contractors, sublicensees or
      distributors of Product. In addition, ISIS will participate as required in
      resolving regulatory concerns. ISIS will be responsible for maintaining
      current technical information needed to support such submissions of
      Registrations, and accordingly will promptly provide ATL with advance
      notification of all changes in such technical information required to be
      filed as amendment(s) to CMC. All such activities will be at ATL's
      expense, which will be agreed to in advance by the parties.

12.2  The mutual goal of ISIS and ATL will be to maintain an integrated approach
      to the content and timing of all submissions of Registrations made by ATL
      in an effort to obtain and maintain regulatory approvals of a Product. To
      ensure this mutual goal is met, with respect to issues pertaining to API
      or to a Product, ISIS will provide to ATL the right to review and
      reference all authorizations, certificates, methodologies and
      specifications in the possession or under the control of ISIS relating to
      the pharmaceutical/technical

                                       16



      development and Manufacture or any component thereof to the extent needed
      for ATL's filings of Registrations.

                          INDEMNIFICATION AND INSURANCE


13.1  INDEMNIFICATION

(a)   ISIS will defend, indemnify and hold harmless ATL, its Affiliates
      and their respective directors, officers, employees and agents, and
      their respective successors and permitted assigns, from any and all
      claims, actions, causes of action, liabilities, losses, damages,
      costs or expenses, including reasonable attorney's fees, which arise
      out of or relate to claims that may be brought or instituted against
      them by Third Parties to the extent based upon or arising out of (i)
      the failure by ISIS to meet the warranties set forth in Article 10;
      (ii) a material breach by ISIS of its obligations set forth in this
      Agreement; or (iii) gross negligence or willful misconduct of ISIS,
      its officers, employees and agents in the performance of its
      obligations hereunder.

(b)   ATL will defend, indemnify and hold harmless ISIS, its Affiliates
      and their respective directors, officers, employees and agents, and
      their respective successors and permitted assigns, from any and all
      claims, actions, causes of action, liabilities, losses, damages,
      costs or expenses, including reasonable attorney's fees, which arise
      out of or relate to claims that may be brought or instituted against
      them by Third Parties to the extent based upon or arising out of (i)
      a material breach by ATL of its obligations set forth in this
      Agreement; or (ii) gross negligence or willful misconduct of ATL,
      its officers, employees and agents in the performance of its
      obligations hereunder.

13.2  CLAIMS

      If a claim is made against a party entitled to indemnification under this
      Article 13, and if that party intends to seek indemnification with respect
      thereto under this Article 13, the party seeking indemnification (the
      "Indemnitee") will promptly notify the indemnifying party (the
      "Indemnifying Party") of such claim. The Indemnifying Party will defend,
      negotiate and settle such claim, and the Indemnitee will cooperate with
      the Indemnifying Party in connection therewith. The Indemnitee may
      participate in the defense of any claim with counsel of its own choice and
      at its own expense. Neither party will settle or compromise any such claim
      without the other party's prior written consent, which consent will not be
      unreasonably withheld. The indemnity agreement in this Article 13 will not
      apply to amounts paid in settlement of any claim if such settlement is
      effected without the consent of the Indemnifying Party, which consent will
      not be unreasonably withheld. Failure of the Indemnitee to deliver notice
      to the Indemnifying Party within a reasonable time after becoming aware of
      a claim will not relieve the Indemnifying Party

                                       17



      of any liability to the Indemnitee pursuant to this Article 13, except to
      the extent such delay prejudices the Indemnifying Party's ability to
      defend such claim.

13.3  INSURANCE

      Each party will maintain during the term of this Agreement and for [***]
      thereafter, at its own expense, (i) commercial general liability
      insurance, including contractual liability coverage, with a minimum limit
      of [***] per occurrence and [***] annual aggregate; (ii) property
      insurance with a minimum limit of [***]; and (iii) statutory workers'
      compensation coverage as required by law.

                              TERM AND TERMINATION


14.1  TERM

      This Agreement will be effective as of the Effective Date, and unless
      sooner terminated as provided herein, will continue in effect until
      December 31, 2006, unless extended by mutual agreement of the parties.

14.2  TERMINATION BY EITHER PARTY

This Agreement may be terminated with written notice by either party at any time
during the term of this Agreement:

(a)   if the other party is in breach of its material obligations hereunder and
      has not cured such breach within 90 days after written notice requesting
      cure of the breach has been given; provided, however, in the event of a
      good faith dispute with respect to the existence of a material breach, the
      90-day cure period will be tolled until such time as the dispute is
      resolved pursuant to Section 16.6; or

(b)   upon the filing or institution of bankruptcy, reorganization,
      liquidation or receivership proceedings by the other party or upon
      an assignment of a substantial portion of the assets for the benefit
      of creditors by the other party; provided, however, in the case of
      any involuntary bankruptcy proceeding such right to terminate will
      only become effective if the party consents to the involuntary
      bankruptcy or such proceeding is not dismissed within 90 days of the
      filing thereof.

14.3  TERMINATION OF COLLABORATION AND LICENSE AGREEMENT

      This Agreement will automatically terminate in the event the Collaboration
      and License Agreement is terminated for any reason.

                                       18




14.4  PAYMENT OF OUTSTANDING DEBTS

      Upon expiration or termination of this Agreement for whatever reason, ATL
      and ISIS will settle all outstanding invoices or monies owed to the other
      party in accordance with the terms of this Agreement.

14.5  EFFECT OF TERMINATION OR EXPIRATION

(a)   If this Agreement is terminated by ATL pursuant to Section 14.2(a),
      all orders will be automatically cancelled and ISIS will terminate
      the Manufacture of API as soon as practicable. ATL will have the
      option but not the obligation to (i) purchase all quantities of API
      stored at ISIS by paying the price of API, as applicable, as
      provided in Section 5.1, and (ii) undertake the Manufacture of API
      or seek a Third Party to do such Manufacture.  If ATL undertakes to
      Manufacture or have Manufactured API, then ISIS will continue the
      transfer of technology pursuant to Article 6 on an expedited basis,
      at ATL's expense.

(b)   If this Agreement is terminated by ATL pursuant to Section 14.2(b), ATL
      (i) will purchase all quantities of API stored at ISIS by paying the price

      right to undertake the Manufacture of API or seek a Third Party to do such
      Manufacture.

(c)   If this Agreement is terminated by ISIS pursuant to Section 14.2(a), ISIS
      will have the option but not the obligation to supply under all
      outstanding quantities set forth in the Production and Delivery Plan at
      the API Supply Price. If ISIS elects to so supply, ATL's payment
      obligations relating thereto including, without limitation, those set
      forth in Section 5.1 will continue to apply until all outstanding
      obligations of ATL to ISIS are fulfilled.

(d)   If this Agreement is terminated pursuant to Section 14.3, all
      outstanding quantities of API set forth in the Production and
      Delivery Plan will be automatically cancelled and ISIS will
      terminate the Manufacture of API as soon as practicable.  In
      addition, ATL will be responsible for all other Manufacturing costs
      associated with API pursuant to Section 5.1 at the time of
      termination.  Notwithstanding the foregoing, ISIS will use its best
      efforts to mitigate any costs payable by ATL under this Section
      14.5(d).

(e)   If this Agreement expires pursuant to Section 14.1, ATL will purchase all
      API ordered by ATL during the term of this Agreement. ISIS will Deliver
      such API in accordance with Section 5.2.

                                  MISCELLANEOUS


16.1  FORCE MAJEURE

      Neither party will be held liable or responsible to the other party nor be
      deemed to have defaulted under or breached the Agreement for failure or
      delay in fulfilling or performing any term of the Agreement when such
      failure or delay is caused by or results from causes beyond the reasonable
      control of the affected party including without limitation embargoes, war,
      acts of war (whether war be declared or not), insurrections, riots, civil
      commotions, strikes, lockouts or other labor disturbances, or acts of God.
      The affected party will notify the other party of such force majeure
      circumstances as soon as reasonably practical and will make every
      reasonable effort to mitigate the effects of such force majeure
      circumstances.

16.2  ASSIGNMENT

      validity, legality and enforceability of the remaining provisions
      contained herein will not in any way be affected or impaired thereby,
      unless the absence of the invalidated provision(s) adversely affect the
      substantive rights of the parties. The parties will in such an instance
      use their

                                       20

---------------------------------------------------------------- ENTITY NUMBER OF ATL SHARES ---------------------------------------------------------------- Polychip 54.375 million ---------------------------------------------------------------- Syngene 54.375 million ---------------------------------------------------------------- Murdoch Interests 11.250 million ---------------------------------------------------------------- Total 120 million ----------------------------------------------------------------
(b) It is anticipated that, after the ASX Listing of ATL, ATL will: (i) be capitalised as to approximately 190 million to 215 million ATL Shares; and (ii) have granted between 105 million Options and 117.5 million Options. (c) It is intended that ATL Shares will be offered to the public for a subscription price of 20 Australian cents per ATL Share, with a free Option attaching to each ATL Share at the rate of 1 Option for every 2 ATL Shares issued. (d) It is intended that, after the ASX Listing of ATL, the ATL Shares issued and Options granted by ATL will be as follows:
---------------------------------------------------------------- PARTY NUMBER OF ATL SHARES NUMBER OF OPTIONS ---------------------------------------------------------------- Polychip 54.375 million ---------------------------------------------------------------- Syngene 54.375 million ---------------------------------------------------------------- Murdoch Interests 11.250 million ----------------------------------------------------------------

*The number of Options to be granted to Circadian Shareholders and Syngene Shareholders respectively are approximate only, based on the issued capital of each of Circadian and Syngene as at the Record Date.

Each Option is exercisable at any time after the date of grant to a date up to and including 30 November 2006. 2. If the Option is not exercised on or prior to the expiry of the Option Period, the Option shall lapse. 3. The Options may be exercised wholly or in part by giving notice in writing ('NOTICE OF EXERCISE') to the Board at any time during the Option Period. 4. Options shall only be exercisable in multiples of 100. Within 10 business days of the exercise of the Option the Company shall apply for the shares to be admitted for quotation on the Official List of Australian Stock Exchange Limited. 5. The exercise price for each Option is $0.20 per share ('EXERCISE PRICE') and is payable immediately on exercise. 6. On receipt by the Company of the Notice of Exercise and payment of the relevant Exercise Price, the Company must, within 14 days, issue to the Option Holder the number of Shares in respect of which the Option is exercised and despatch the relevant share certificate or other appropriate acknowledgment as soon as reasonably practicable thereafter. 7. Shares issued on the exercise of any Options will rank equally in all respects with the then existing issued ordinary fully paid shares in the Company and will be subject to the provisions of the Constitution of the Company. 8. An Option does not confer rights to participate in new issues of securities of the Company, unless the Option Holder has first exercised the Option. 9. Adjustments to the number of shares over which Options exist and/or the Exercise Price will be made to take account of changes to the capital structure of the Company by way of pro rata bonus and cash issues as follows: (a) Pro-Rata Cash issues Where a pro-rata issue is made (except a bonus issue) to the holders of underlying securities, the Exercise Price of an option may be reduced according to the following formula: O' = O - E[P-(S+D)] ---------- N + 1 where: O' = the new exercise price of the option. O = the old exercise price of the option. E = the number of underlying securities into which one option is Exercisable. P = the average Market Price per security (weighted by reference to volume) of the underlying securities immediately prior to the time of determining entitlements to participate in the issue. 11 S = the Subscription price for a security under the pro rata issue. D = the Dividend due but not yet paid on the existing underlying securities (except those to be issued under the pro rata issue). N = the Number of securities with rights or entitlements that must be held to receive a right to one new security.

    AMGEN AND ISIS PHARMACEUTICALS TO COLLABORATE ON ANTISENSE DRUG DISCOVERY

THOUSAND OAKS and CARLSBAD, CA -- December 13 -- Amgen (NASDAQ: AMGN) and Isis
Pharmaceuticals, Inc. (NASDAQ: ISIP) announced today that the companies have
entered into a three-year collaboration to discover new antisense drugs. The
therapeutic area of research and financial terms of the transaction were not
disclosed.

Amgen and Isis will collaborate on antisense drugs utilizing Isis' proprietary
second-generation chemistry, called 2'-O-methoxyethyl, to inhibit several gene
targets. Antisense technology is a novel drug discovery method. Antisense drugs
work at the genetic level to interrupt the process by which disease-causing
proteins are produced.

Amgen has the right to develop and commercialize antisense drugs resulting from
the collaboration. If drugs from the collaboration are successful, Isis will
receive milestone payments upon key clinical and commercial achievements, as
well as royalties on sales.

"We are intrigued with the possibility that through this collaboration with
Isis, a leader in antisense technology, we may be able to provide important
medicines for unmet medical needs," said Roger Perlmutter, Amgen's Executive
Vice President for Research and Development.

and reimbursement policies may affect the development, usage and pricing of
products.

In addition, while Amgen routinely obtains patents for products and technology,
the protection offered by patents and patent applications may be challenged,
invalidated or circumvented by competitors.

Because forward-looking statements involve risks and uncertainties, actual
results may differ materially from current results expected by Amgen. Amgen is
providing this information as of December 13, 2001 and expressly disclaims any
duty to update information contained in this press release.




This press release also contains forward-looking statements concerning Isis
Pharmaceuticals and the potential of antisense drugs and Isis' current and
future relationship with Amgen. Such statements are subject to certain risks and
uncertainties, particularly those inherent in the process of discovering,
developing and commercializing drugs that are safe and effective for use as
human therapeutics and financing such activities. Actual results could differ
materially from those projected in this release. As a result, you are cautioned

   ISIS PHARMACEUTICALS AND CIRCADIAN TECHNOLOGIES FORM ANTISENSE THERAPEUTICS
                                     LIMITED

    NEW AUSTRALIAN COMPANY FURTHERS ISIS' STRATEGY TO BROADEN APPLICATION OF
                              ANTISENSE TECHNOLOGY

Carlsbad, CA, USA and Melbourne, Australia, December 19, 2001 - Isis
Pharmaceuticals, Inc. (NASDAQ: ISIP) and Circadian Technologies Limited (ASX:
CIR), a leading Australian biotechnology commercialization firm, announced today
the companies have collaborated to create Antisense Therapeutics Limited (ATL).
Isis and Circadian have established this new Australian-based biotechnology
company to focus on the discovery and development of antisense drugs. ATL will
further the application of Isis' antisense technology platform in new markets.
ATL was listed on the Australian Stock Exchange (ASX) today under the symbol
ANP, successfully completing its initial public offering.

As part of establishing ATL in the antisense field, Isis has licensed to ATL
ISIS 107248, an antisense inhibitor to CD 49d, a sub-unit of VLA-4 (Very Late
Antigen-4). Treatment by inhibition of VLA-4 has been demonstrated to have
positive effects in animal models of a number of inflammatory diseases such as
multiple sclerosis. Isis will complete the required preclinical studies for ISIS
107248 and will manufacture drug for human clinical trials at ATL's expense. ATL
will undertake future clinical development and commercialization of the
compound.

Isis and ATL will also participate in a five-year antisense drug discovery and
development collaboration, which includes ATL's use of GeneTrove's-TM- gene
functionalization services for a limited number of targets. ATL will pay Isis
for access to the company's antisense expertise and for research and
manufacturing services conducted during the collaboration. In addition, ATL will
pay to Isis royalties on antisense drugs discovered and developed within the
partnership. Isis owns approximately 14 percent of ATL equity and holds options
for additional shares. Isis' Chairman and CEO Stanley T. Crooke, M.D., Ph.D., is
a member of ATL's Board of Directors.

"In partnership with Circadian, we are very pleased to have formed a new company
focused solely on exploiting antisense technology as a drug discovery and

discover more potential drug candidates than we can afford to develop. ATL
represents a strategic move to broaden the reach of antisense drugs, while
minimizing financial obligations for us and our shareholders."

To build its business, ATL will engage in antisense drug discovery and
development collaborations with academic research institutions throughout
Australia, including the prestigious Murdoch Childrens Research Institute based
in Melbourne. Murdoch Childrens Research Institute will contribute key specific
intellectual property and expertise to ATL's antisense research efforts. In the
future, ATL plans to work with additional corporate partners.

"Antisense is a revolutionary drug discovery platform that has progressed
significantly over the last decade and is now prime for broad application. We
look forward to working with Isis, the undisputed leader in antisense, as our
key technology partner. We have created a powerful team and business plan to
expand the investigation and development of this important platform technology
into new therapeutics for patients in need," said Chris Belyea, ATL's founding
Chief Executive Officer.

ATL's IPO raised A$13 million (Australian dollars), or US$6.5 million. Circadian
directly and indirectly holds 36 percent of ATL issued capital.

"In recent years we have worked successfully to establish several listed
Australian biotechnology companies and we are delighted to be involved in this
collaboration with Isis who we regard as the pioneer of antisense technology,"
said Leon Serry, Circadian's Chief Executive Officer.

   ISIS PHARMACEUTICALS ESTABLISHES NEW SUPPLY AGREEMENT AND BROADENS LICENSE
                     TO KEY ANTISENSE INTELLECTUAL PROPERTY

Carlsbad, CA and Coraville, IA December 27, 2001 -- Isis Pharmaceuticals, Inc.
(NASDAQ: ISIP) announced today it has established a long-term research-scale
antisense inhibitor supply agreement with Integrated DNA Technologies, Inc.
(IDT). IDT is a leading supplier of antisense inhibitors used in research.
Additionally, Isis has further solidified its intellectual property leadership
position in antisense technology by broadening its license to certain antisense
patents.

In the long-term supply agreement Isis has initiated with IDT, IDT will
manufacture research-scale antisense inhibitors and research reagents to Isis
specifications. The agreement enables Isis to meet increasing demand for
functional genomics services that its GeneTrove division provides to a growing
number of major pharmaceutical and biotechnology customers. Isis will pay IDT $5
million toward Isis' future purchase of antisense inhibitors from IDT. The
transaction provides IDT with financing for the company's operations expansion.

Consistent with Isis' goal of broad control of intellectual property associated
with antisense technology, Isis has expanded its existing licensing agreement
with IDT on certain patents, which are useful in functional genomics and in
making certain antisense drugs. The expanded license allows Isis to exclusively
sublicense this intellectual property for functional genomics purposes. The
agreement also eliminates milestone payments and significantly reduces royalty
rates associated with commercialized second-generation antisense drugs. Isis
will pay IDT $4.9 million for the broadened intellectual property license.

Isis' intellectual property estate is comprised of nearly 900 issued patents
that Isis owns or exclusively licenses, covering RNA-based drug discovery and
development. The company's functional genomics suite of patents is made up of
approximately 50 patents and applications. This functional genomics suite of
patents broadly covers the use of RNA/DNA oligonucleotides, or antisense
inhibitors, in gene functionalization and target validation, including:
chemistries; antisense inhibitor designs called "motifs;" methods of use of
antisense inhibitors; and mechanisms of action by which antisense inhibitors
inactivate an RNA target.

"Our GeneTrove division has enjoyed tremendous success this year, adding Celera,
Lilly and Chiron to its roster of collaborators. The supply agreement we've
initiated augments our capacity to support these programs and continue to build
our GeneTrove business," said B. Lynne Parshall, Isis Executive Vice President
and Chief Financial Officer. "Importantly, this transaction enhances Isis'
intellectual property licensing program and supports our control over
second-generation antisense drugs, which we believe offer broad potential to
treat a wide range of diseases. It also improves the economics of the
second-generation drugs we develop."

"IDT is pleased to enter into this licensing agreement with an established
partner like Isis, and to continue to be a principle supplier of antisense
inhibitors and research reagents for Isis' research and development programs,
and to Isis' growing list of licensees and collaborators," said Joseph A.
Walder, M.D., Ph.D., President and CEO of IDT. "Importantly for IDT, this
transaction fortifies our financial position and facilitates our growth to meet
market demand in the ever-expanding global life sciences market."
