For Immediate Release from Seneca Capital; Saving Dynegy: from More Scorched Earth

NEW YORK--(BUSINESS WIRE)--Seneca Capital, the second largest shareholder of Dynegy Inc. (NYSE: DYN) with a 12% economic interest (including 9.3% voting common stock) is writing to address the latest chapter in Dynegy’s scorched-earth campaign. Seneca Capital believes the materials disseminated by Dynegy on Friday represent yet another unfortunate attempt to corral support for a sale of the company at a low point in the cycle – a process that shareholders have now rejected four times. Seneca Capital urges Dynegy shareholders NOT TO TENDER their shares at $5.50 per share – it is the WRONG PRICE at the WRONG TIME for the WRONG REASONS. Seneca Capital believes that once the IEP tender is defeated this Friday and the merger agreement is subsequently dissolved, an overhang will be removed that will clear the path for investors to participate in the positive changes (including Board/management alignment with shareholders) at Dynegy that Seneca Capital is working vigorously to advance.

EVEN MORE “SCORCHED EARTH” TACTICS??: Seneca Capital is surprised and disappointed that Dynegy is yet again (in a release transparently timed to coincide with FERC approval) attempting to talk down the market’s view of Dynegy’s valuation with its “Getting the Facts Right” campaign – even after shareholders rejected Dynegy’s scorched earth “Blackstone at $4.50 or Bust” campaign last fall. Dynegy’s latest effort to publicly attack its own valuation – a tactic Seneca Capital has not seen in more than 20 years of investing – has misinterpreted several important “facts”. In discussing cost savings, Dynegy fails to acknowledge that Seneca Capital’s sum-of-parts analysis has already applied the $50 million incremental cost savings identified by management (which was publicly disclosed for the first time after the Blackstone merger was announced) to the SG&A portion of the sum-of-parts analysis – correcting this view of the “facts” would increase the sum-of-parts analysis by as much as $2.00 per share. In addition, Dynegy conveniently excludes more than $150 million of restricted cash and broker margin from its net debt calculation (these items are reported on Dynegy’s September 30^th balance sheet) and fails to account for more than $90 million of pay-down of lease/project bonds in Seneca Capital’s net debt calculation – correcting this view of the “facts” would increase the sum-of-parts analysis by more than $2.00 per share. Seneca Capital will be disseminating a slide presentation shortly that debunks Dynegy’s latest “Getting the Facts Right” campaign. It is noteworthy that the last time Dynegy issued a “correction” to Seneca Capital’s valuation that attempted to scare investors into supporting the $4.50 per share proposed Blackstone deal, Dynegy arrived at a negative per share valuation for the company.¹ At least this time, Dynegy has acknowledged that the company has positive equity value.

WHAT ABOUT THE POSITIVE DEVELOPMENTS IN NEW YORK?: While Dynegy leadership appears keen to present a negative picture of Dynegy’s fundamental outlook they have neglected to mention the positive developments on January 28^th at FERC relating to the New York capacity markets. This omission is glaring given Dynegy’s active intervention in FERC’s rulemaking process. The January 28^th ruling by FERC should result in a higher cost of new entry over time for the New York capacity markets – a favorable outcome that Dynegy fought hard to support. Dynegy is also actively lobbying the NY ISO to break-out the separately constrained Lower Hudson Valley zone (where Roseton and Danskammer are located) and the recent FERC ruling could bode well for that proceeding. Dynegy has more than 2,000 MW of un-hedged capacity in New York (excluding the Sithe capacity contract) and therefore every $2/kw-mo change in New York capacity prices could impact Dynegy cash flow by nearly $50 million per year (at a 5x multiple this would be more than $2.00 per share). Seneca Capital believes these are important facts to "get right".

A DIFFERENCE OF ALIGNMENT DRIVES A DIFFERENCE OF OPINION:

	DYNEGY	SENECA CAPITAL
Valuation	Sell at $4.50, $5.00, $5.50 per share in cash ($0.90, $1.00, $1.10 per share pre-reverse split)…to a “financially stronger entity”??	Do not sell for $4.50, $5.00, $5.50…$6.00(!) at low point in cycle…regardless of buyer’s “financial strength” Dynegy underperformed IPPs by ~30% and the market by ~45% since March ’10 reverse split announcement
Alignment / Objectives	$35mm change-of-control benefits/severance	Largest non-conflicted shareholder Only “objective” is to profit as stock rises
Judgment	In 2008, chose not to hedge power prices when gas was over $13/mcf In August ’09 purchased ~30% of Dynegy stock for $9.65/sh from LS Power Feb 2011: Board’s “years of experience” provide superior “collective understanding of Dynegy’s earnings potential”??	Gravely concerned with Dynegy leadership’s judgment and credibility Strongly endorse the value-generating experience and alignment of Board nominees Hunter Harrison (pioneering railroad executive) and Jeff Hunter (successful power industry veteran)
Board Ownership	16,000 shares purchased Ownership limits “objectivity”?^2	Nominee Hunter Harrison bought 500,000 shares at an average price above BX deal (after it was announced) at $4.50; Jeff Hunter has committed to own 300,000
Poison Pill	Implemented only AFTER trying to sell Dynegy Protecting “control premium” after trying to sell the entire company at $4.50 per share?	Seeking waiver to acquire shares above $5.50 per share – more than 22% higher than the “control premium” the Board accepted from BX in August Offered to commit not to squeeze out minorities below $5.50 per share
Shareholder Votes	Virtually unprecedented “recess” Incremental $16mm break-fee to BX and $16mm break-fee to IEP despite shareholder opposition to modest bump	74% of shareholders did not support Blackstone deal 95%+ of non-affiliated shares twice rejected IEP deal
Shareholder Funds	Willing to spend more than $100mm (>15% of deal price) to sell the company	Implore Board to stop spending corporate assets in the face of shareholder opposition
The $2.78 Scarecrow/ Flawed Starting Point	Argued that without Blackstone the share price could crash below $2.78 per share Now issuing materials that attempt to scare investors regarding the share price post-IEP tender	Dynegy stock declined 64% from the reverse split announcement in March ’10 to a nearly all-time low of $2.78/sh at August ’10 BX deal announcement Inexplicably plummeted nearly 25% in the week prior to the BX deal Important new facts have come to light ($50mm of cost savings, NRG value validation of California plants, etc) that represent more than $4.00 per share BX and IEP offers create artificial ceiling – strong fundamental interest once tender is defeated
Liquidity	Changed from pre-Blackstone August 6^th statement of “simple, flexible capital structure” to scorched earth “Blackstone or Bust” campaign	Liquidity issue is red herring – substantial unutilized lien capacity and no major maturities until 2015 NO NEED TO ISSUE EQUITY
Natural Gas “Confusion”	Gas sensitivity ($165mm) assumes gas plants set the power price in all hours in markets where Dynegy’s coal plants are located??	Gas exposure is asymmetric – forward margin improved despite decline in gas Gas plants set power price roughly 15% of time for Dynegy’s Midwest coal plants Dynegy makes electricity not natural gas
Sale Process	Attempted to sell company in two ill-structured go-shop processes during late August and December holiday season Abandoned promised “careful standalone review” in gaining support from IEP affiliate (largest holder/ outspoken critic) against consent solicitation	Why abandon “careful standalone review” and presume company should be sold for cash at a low point in cycle? Why create barriers to participation? – even IEP wouldn’t sign CA until after deal announced
Financial Advisors	Dynegy is selling the company at a “fair price” at $4.50, $5.00, $5.50/sh	Financial advisors receive $13mm in additional fees if Dynegy is sold
Post IEP Tender	“At work taking actions and preparing plans for remaining an independent company” Comfortable with compensation structures creating misalignment	Grave concerns regarding Dynegy leadership Pursuing a consent solicitation to replace the Chairman and one other Board member with Hunter Harrison and Jeff Hunter Will not stop fighting until proper alignment with shareholders is achieved…and value realized

RESPECTING SHAREHOLDERS’ VOICE: Shareholders own the company, not the Board. Dynegy shareholders have twice overwhelmingly rejected the IEP tender offer and Seneca Capital calls upon the Dynegy Board to respect shareholder views and work with Seneca Capital to reconstitute the Board with individuals who believe in the value proposition for Dynegy and are aligned with shareholders. Seneca Capital has more conviction than ever that selling Dynegy at a low price at this point in the cycle does not reflect Dynegy’s industry leading operating and financial leverage to a commodity recovery.

PURSUING CHANGE: Seneca Capital continues to vigorously pursue a consent solicitation to protect shareholder value by replacing the Chairman and one other Dynegy Board member with Hunter Harrison, a pioneering railroad executive, and Jeff Hunter, a successful power industry veteran. Mr. Harrison and Mr. Hunter are fully aligned with the proposition of driving value for Dynegy shareholders – Mr. Harrison has already purchased 500,000 shares personally and Mr. Hunter has committed to purchase 300,000 shares while serving on the Dynegy Board.

Seneca Capital is working diligently towards achieving definitive status for its preliminary consent solicitation and filed a revised document this past Friday. Dynegy must provide a record date for the consent solicitation that is no later than 20 days from the date of a request by Seneca Capital. Once the preliminary consent solicitation becomes definitive, Seneca Capital will begin gathering shareholder consents and once consents for a majority of shares outstanding have been collected, Seneca Capital’s nominees must be seated on the Dynegy Board.

Seneca Capital urges shareholders to NOT TENDER their stock for $5.50 per share. It is the WRONG PRICE at the WRONG TIME for the WRONG REASONS.
