Representative Matters

  • Represented an ecommerce company in prosecuting a breach of contract claim against one of its former customers, which arose out of the customer’s failure to pay $8 million in fees for ecommerce fulfillment and shipping services. Granting summary judgment, the JAMS arbitrator found that the team met its burden to establish that the undisputed factual record and plain and unambiguous terms of the various agreements required the customer to pay all undisputed invoices on time and did not provide for a right of set-off. The arbitrator also dismissed the customer’s counterclaims in awarding damages of just under $11 million.

  • Represented the Stockholders' Representatives of a pharmaceutical company in connection with the receipt and distribution to the former shareholders of a $150 million "milestone" payment from another pharmaceutical company. The milestone payment arose out of the March, 2016 approval by the U.S. FDA of a biological drug that treats a severe form of asthma.
