On November 30, 2017, Galena sent a letter to stockholders that, in pertinent part, stated as follows:
Dear Stockholders:
We previously
mailed you a proxy statement/prospectus/consent solicitation statement, dated November 6, 2017, regarding the special meeting of stockholders to be held on December 15, 2017 (Special Meeting). We are seeking your approval of a
business combination transaction in which the businesses of Galena Biopharma, Inc. and SELLAS Life Sciences Group Ltd (SELLAS) will be combined (the Merger).
As we have disclosed in the materials sent to you, if the Merger is not completed, Galena may elect to liquidate its remaining assets and there
can be no assurances as to whether any cash would be available to distribute to Galenas stockholders after paying Galenas debts and other obligations. We believe a liquidation of Galena would be the worst possible outcome for
Galenas stockholders and, therefore, recommend that stockholders approve the proposals discussed below.
There are ten proposals for
consideration at the Special Meeting (the Proposals). We note the following regarding the Proposals:
|
|
|
Proposals 1, 2 and 3 must be approved by stockholders for the Merger to occur;
|
|
|
|
If approved, Proposal 4 would provide the continuing company with the ability to raise the necessary equity capital in the future, within certain parameters, without obtaining further stockholder approval;
|
|
|
|
Proposal 5 relates to a new equity incentive plan and Proposal 6 relates to a new employee stock purchase plan, both of which are expected to help the continuing company attract and retain employees, directors and
consultants;
|
|
|
|
Proposal 7 relates to the amendment of Galenas bylaws so they are more in accordance with the standard bylaws among public companies; and
|
|
|
|
Proposal 8 relates to an amendment to Galenas amended and restated certificate of incorporation to allow the board of directors to adopt, amend or repeal Galenas bylaws, which is more in line with standard
bylaws of public companies;
|
|
|
|
Proposal 9 relates to a
non-binding,
advisory vote on the compensation that will be paid or may become payable to Galenas named executive officers in connection with the
Merger;
|
|
|
|
Proposal 10 relates to adjourning the Special Meeting in the event there are not sufficient votes to approve the Proposals mentioned above. Please refer to the proxy statement/prospectus/consent solicitation statement
for a complete description of each of the Proposals.
|
The Galena board of directors believes that approval of each of the
Proposals is important to Galena and the ongoing business of the continuing company after the Merger. Accordingly, the Galena board of directors unanimously recommends that stockholders
vote FOR
each of the Proposals.
Your vote is very important. It is imperative that you vote your shares, as unvoted shares may prevent the approval of the Merger.
[In addition to calling Mackenzie at (800)
