Amendment to Employment Offer Letter between BakBone Software, Inc. and Ken Horner

Exhibit 10.17

We are pleased to be able to inform you about an amendment to your current terms and conditions of employment with BakBone Software, Inc.

This change is in recognition of your continuous commitment to BakBone Software as an executive of this company and of the fact that recent offers to company executives at this level have included similar language.

Therefore, the following paragraphs are hereby added to your employment letter with BakBone:

“If, at any time during your employment with BakBone, you are terminated for reasons other than cause, you will be entitled to six (6) months severance pay of your base salary payable in a lump sum, conditional upon a signed settlement and release agreement within thirty (30) days following the date of your termination. In no case shall the severance pay in the preceding sentence be paid later than the date that is 2 ¹/2 months following the end of the calendar year in which you are terminated.

Notwithstanding any inconsistent provision of this offer of employment, if you are a “specified employee” within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) at the time of your termination, then the portion of your severance pay, together with any other severance payments or benefits that, in each case, may be considered deferred compensation under Code Section 409A, that would otherwise be payable within the six (6) month period following your termination will be paid in a lump sum on the date six (6) months and one (1) day following the date of your termination (or the next business day if such date is not a business day) or, if earlier, the date of death, provided you have complied with the requirements for such payment. Notwithstanding anything herein to the contrary, no actions taken pursuant to this paragraph shall reduce the total amount of payments and benefits owed to you and to be paid to you under this offer of employment.”

These new paragraphs supersede and replace the paragraph that was added to your employment letter on September 28, 2006. All other terms and conditions of your employment letter remain in full force and effect and unchanged by this amendment.

I hope you agree that this change is equitable and fair and enhances the terms of your employment as an executive of BakBone Software. Please indicate your acceptance of this change by signing below and returning one original copy to me.

Thank you

Jim Johnson

President and Chief Executive Officer
