General Motors Corp. (GM) said Monday it will cut 21,000 hourly jobs and eliminate its Pontiac brand by the end of next year as part of a stepped-up restructuring plan.

The auto maker is also starting an exchange offer for $27 billion of its unsecured public notes as part of its restructuring plan as the company looks to become viable, saying a successful exchange offer would allow it to restructure out of bankruptcy court.

The company is offering to exchange 225 common shares for each $1,000 principal amount of outstanding notes. The stock closed Friday at $1.69 a share and shares were recently up 11% at $1.87 in premarket trading.

The exchange will commence only if 90% of bondholders agree to the terms. Under the plan, if GM fails to get adequate participation, it will file for bankruptcy protection.

GM, which is surviving on federal loans, is racing to restructure by June 1 under close watch of the Obama administration.

The U.S. Treasury will extend an additional $11.6 billion to GM, in addition to $15.4 billion in existing loans. The government will forgive half the debt in exchange for equity in a restructured GM.

GM, in setting forth unattractive terms for a bond exchange and requiring almost compete participation, has stepped up the likelihood for a Chapter 11 filing on June 1 without further government intervention.

The company said it will focus on four core brands in the U.S. - Chevrolet, Cadillac, Buick and GMC - as it looks to make fewer different models and focus on product development programs.

It will also restructure its U.S. dealer organization, reducing its U.S. dealer count by more than 40% by the end of next year, a reduction of 500 more dealers four years sooner than its earlier viability plan.

Chief Executive Fritz Henderson said the company is taking "tough but necessary actions" that are critical to GM's long-term viability.

The company added that negotiations regarding contract changes with the United Auto Workers union are still ongoing.
