Information and will only be used by ABG in connection with the exploitation of the license rights granted in Article IV. All Licensed Know-How will remain owned by Epoch. Similarly, ABG will transfer certain know-how to Epoch to the extent
necessary for Epoch to make Bare Probes for ABG. Such know-how will include, but not be limited to, information relating to the synthesis, purification, and characterization of oligonuclotide compounds, and automated systems for configuring orders
of custom sequence oligonucleotides. All such know-how is considered to be ABGs Confidential Information and will only be used by Epoch in connection with Epochs obligations under this Agreement, and not for any other purpose. All such
know-how will remain owned by ABG.

(b) Within sixty (60) days following the 2ndAmendment Date, Epoch shall transfer to ABG all MGB Intermediates Manufacturing Know-How (in existence now or through February 28, 2006) necessary for
ABG to make and have made MGB Intermediates owned or Controlled by Epoch as of the Effective Date or thereafter including, but not limited to, the information set forth on Exhibit D attached hereto and incorporated herein. Epoch will provide ABG
such MGB Intermediates Manufacturing Know-How on CD-ROM or other medium reasonably acceptable to ABG. Without limiting the foregoing, Epoch will

provide ABG with instruction and assistance at ABGs facilities (and provide ongoing cooperation and
responses to ABGs inquiries) with respect to such MGB Intermediates Manufacturing Know-How to ensure that ABG is fully able to exploit and utilize such MGB Intermediates Manufacturing Know-How under this Agreement and the Quencher Agreement.
For the avoidance of doubt, ABG will not have the right to sell or otherwise incorporate into a Licensed Product such MGB Intermediates made by ABG or by a contractor of ABG unless Epoch fails to supply at least ninety-five percent (95%) of
ABGs forecast requirements of MGB Intermediates for more than two (2) months after receipt of written notice from ABG of Epochs failure to so supply.

(c) Within sixty (60) days following the 2ndAmendment Date, Epoch shall
transfer to ABG all Modified Base Know-How (in existence now or through February 28, 2006) necessary for ABG to make and have made MGB Intermediates owned or Controlled by Epoch as of the Effective Date or thereafter. Epoch will provide ABG
such Modified Base Know-How on CD-ROM or other medium reasonably acceptable to ABG. Without limiting the foregoing, Epoch will provide ABG with instruction and assistance at ABGs facilities (and provide ongoing cooperation and responses to
ABGs inquiries) with respect to such Modified Base Know-How to ensure that ABG is fully able to exploit and utilize such Modified Base Know-How under this Agreement and the Quencher Agreement.



|10. | Section 7.05 of the MGB Agreement is hereby amended to add the following Section:

Patents, Related Patents, MGB Intermediates Manufacturing Know-How or Modified Base Know-How. To the extent that the foregoing representation and warranty in this part (f) is inaccurate, then Epoch and Nanogen hereby agree that any such
patents, patent applications or know-how shall be deemed to be, as of the Effective Date, within the definition of Licensed Patents, Related Patents, MGB Intermediates Manufacturing Know-How and Modified Base Know-How, respectively.



|11. | Section 12.08 of the MGB Agreement is hereby amended in its entirety to read as follows:
|--- | ----------------------------------------------------------------------------------------

Assignment. This Agreement and the licenses herein granted will be binding upon and inure to the benefit of the successors in interest of the
respective Parties. Neither Party will have the power to assign this Agreement nor any interest hereunder without the written consent of the other, such consent not to be unreasonably withheld, provided, however, that ABG or Epoch may assign this
Agreement or any of its rights or obligations hereunder to any Affiliate or to any third party with which it may merge or consolidate, or to which it may transfer all or substantially all of its assets or business to which this Agreement relates,
without obtaining the consent of the other Party, subject to such assignee assuming all liabilities and obligations under the Agreement.
