Under the rights offering, Zion will distribute non-transferable subscription rights to holders of Zion's common stock on the record date of June 15, to purchase their pro-rata portion of about 6.25 million Units of Zion's securities. Each Unit will consist of one share of Zion's common stock and warrants to purchase two additional shares of Zion's common stock at an exercise price of $3.50 per share. Under the rights offering, stockholders of record will have the right to subscribe for one Unit for every four shares of common stock owned on the record date, equivalent to 0.25 subscription rights for each share of common stock owned on the record date.

Each whole subscription right will entitle the stockholders of record on the record date to subscribe for one Unit at the per Unit purchase price of $5.00. The warrant will be exercisable for a one-year period beginning on the closing date after the rights offering expires. The rights offering is planned to commence as soon as practicable after the record date and to continue through 5:00 p.m. Eastern Standard time on July 25, subject to Zion's right to extend the offering in its sole discretion. The rights offering will also include an over-subscription privilege, entitling a stockholder who exercises all of their basic subscription privilege the right to purchase additional Units that remain unsubscribed at the expiration of the rights offering, subject to the availability and pro-rata allocation of securities among stockholders exercising their over-subscription right.

AEterna Zentaris Inc. (AEZS) stock grew 8.33 percent to $2.47 in the pre-market trading.

Exelixis, Inc. (EXEL) stock gained 5.29 percent to $9.15 in the pre-market trading. The company reported updated interim data from the fully enrolled cohort of patients with metastatic castration-resistant prostate cancer (CRPC) treated with cabozantinib (XL184) in a phase 2 adaptive randomized discontinuation trial (RDT). The data provides additional patient experience and longer-term follow-up showing that cabozantinib results in resolution or stabilization of metastatic bone lesions on bone scan in the majority of patients evaluable by this method.

Additionally, cabozantinib treatment relieved or eliminated bone pain in the majority of patients, thus allowing for most who require narcotic analgesic medication to either reduce or eliminate the use of these medicines. Patients with partial or complete resolution of metastatic bone lesions by bone scan were more likely to remain free of disease progression at month 6, experience pain relief, reduce or eliminate their use of narcotic analgesics, achieve tumor regression, and experience marked declines in markers of bone turnover when compared to those who did not achieve bone scan resolution.

SunOpta Inc. (STKL) stock rose 3.84 percent to $7.84 in the pre-market trading. CNBC host Jim Cramer on Friday called SunOpta as a terrific way to speculate on the bull market in healthy eating.
