ANNEX B

Trico to Launch an Offer for All Shares of Active Subsea ASA

•		Trico to offer to acquire outstanding shares of Active Subsea for NOK 22.50 per share
•		Active Subsea board and senior management recommend offer to shareholders

Houston, US and Ålesund, Norway — November 5, 2007

Trico Marine Services, Inc. (Nasdaq: TRMA) (“Trico”) and Active Subsea ASA (NOTC: ASUB) (“Active Subsea”) today announced that Trico intends to make a voluntary offer for all outstanding shares and warrants of Active Subsea. The offer price per share of Active Subsea will be NOK 22.50 paid in cash. The offer values Active Subsea’s equity at approximately NOK 1.31 billion (approximately US$242 million at exchange rates as of November 2, 2007). The board of directors of Active Subsea believes that it is in the best interests of the company’s shareholders to support the offer. All board members in Active Subsea have pre-accepted the offer for the shares they hold in Active Subsea, including options and warrants. The transaction is expected to be completed in the fourth quarter of 2007 and is subject to regulatory and other customary approvals, as well as to Trico receiving valid and unconditional acceptances of the offer from shareholders representing more than 90% of the outstanding shares of Active Subsea.

Active Subsea ASA is a marine supply services company based in Ålesund, Norway with eight medium-sized VS 470 multi-purpose service vessels (“MPSVs”) on order for delivery beginning in 1Q08 through 1Q09. Active Subsea’s vessels are designed to support subsea services, including performing inspection, maintenance and repair work using remotely operated vessels (“ROVs”), dive and seismic support and light construction activities. Active Subsea has already secured three long-term contracts with customers for operations in Brazil and Mexico.

Trico believes the acquisition will provide the following benefits:

•		expands Trico’s ability to offer subsea services with the addition of a fleet of eight versatile vessels, doubling the number of vessels in its fleet capable of such activities,
•		advances Trico’s newbuild program, with 11 DP 2 vessels now scheduled for delivery in 2008 and 2009
•		leverages Trico’s global footprint in growth markets and broadens Trico’s customer base to include subsea service and construction companies,
•		provides opportunities to secure long-term contracts, enhancing earnings stability, and
•		maintains Trico’s financial strength.

Joe S. Compofelice, Chairman and Chief Executive Officer of Trico, stated, “We are extremely excited about this transaction as it is consistent with both the strategic and capital deployment

Execution Version

objectives that Trico has outlined for investors over the past several months. By adding Active Subsea’s versatile VS 470 MPSVs to our fleet, we are able to offer our customers vessels suited for a broad array of subsea services. We will become one of the largest operators of new MPSVs for the growing subsea market. This transaction enhances our newbuild program by providing for near-term deliveries which accelerates cash flow from the vessels and provides an advantage in securing customer contracts. Additionally, this transaction will allow us to further leverage our unique global presence by offering these vessels, which are attractive to customers in each of our international markets. With the acquisition of Active Subsea, we will establish a new division, Trico Subsea, which will be focused on marketing and operating these vessels as well as other vessels in our fleet that are capable of serving the subsea market.”

Robert Welsvik, Chief Executive Officer of Active Subsea, stated, “We believe this transaction recognizes the strategic value of our vessels and represents a fair price for our shareholders. We are pleased to see Active Subsea become the centerpiece of Trico Subsea, and believe that Trico’s global presence and operating expertise will lead to great success in the placement and operations of the vessels.”

Johan Hagenaes, Director of Active Subsea, added, “As a board member and significant shareholder, I believe Trico’s offer reflects fair value and will provide all of Active Subsea’s shareholders with an excellent return on their investment. As a founder of Active Subsea and long-time participant in the offshore industry, I am excited that these vessels will be placed into Trico’s global network and capable hands for the benefit of our customers. I believe that Trico Subsea is an excellent successor to build upon the foundations that Robert, I and others at Active Subsea have created.”

Following the transaction, management of Active Subsea will continue to supervise the construction of the vessels and participate in marketing efforts for a transition period.
