Filed by Denbury Resources Inc. (Commission File No. 001-12935) Pursuant to Rule 425 of the Securities Act of 1933 and deemed filed pursuant to Rule 14a-12 of the Securities Exchange Act of 1934 Subject Company: Penn Virginia Corporation (Commission File No. 001-13283) The following email was distributed on October 29, 2018, by Denbury Resources Inc. to employees of Denbury Resources Inc. Denbury Employees,  Tonight we announced that Denbury will acquire Penn Virginia Corporation. We are extremely excited  about this acquisition and what it means for our future, and I would like to share a few of the details  with you.  Penn Virginia is based in Houston, operating in the Eagle Ford Shale of south Texas. Their production is  mostly oil, and they have about ten years of drilling inventory on their acreage. In the last quarter, Penn  Virginia produced about 22,000 BOE per day, around 75% of that being oil.  The Board and management considered four key strategic objectives in entering into this transaction:  • First, we have been seeking opportunities to add investment diversity. Having the option to invest capital across a more diverse asset base provides greater flexibility, which will prove beneficial over time with volatility in oil prices.  Primary development of Penn Virginia’s Eagle Ford acreage is a perfect example of this diversity, as this development can be economically attractive in a low oil price environment. • Second, we want to enhance our ability to grow production while still delivering free cash flow. I believe the companies that will be most valued by investors will be those able to both grow and generate free cash flow.  This combination with Penn Virginia provides the foundation to accomplish both of those objectives.  Very few companies in our business are able to do the same. • Third, we have the opportunity to be at the forefront of the next frontier for EOR, which is in shale. Several operators are already developing EOR projects in the Eagle Ford, and given our passion for EOR, our technical knowledge, and our experience, we are the obvious and natural leader in shale EOR development. • Fourth, we must continue to improve our financial strength. The combined companies will create a company that will be financially stronger in most ways.  As a result of this combination, we will have a stronger balance sheet, better debt metrics, and will generate more cash flow per share than we would achieve individually. The combined company will have greater size and scale, and when combined with our improving debt metrics should result in a lower cost of capital over time. We expect to complete the transaction in the first quarter of 2019, subject to the approval of Denbury  and Penn Virginia shareholders, certain regulatory approvals and typical closing conditions. Until the  closing of the transaction, Denbury and Penn Virginia will continue to operate as independent  companies.   Materials describing this transaction and what it means for Denbury are available in our press release  and presentation, as well as on our investor call, all of which are available on our website. We will hold a  town hall meeting in Plano to discuss the transaction at 9:00 am (central), which will be webcast to our  field locations. As with any Denbury business, if you receive inquiries from the media regarding the  transaction, please direct the inquiry to John Mayer, Director of Investor Relations. 

I am very excited about what this transaction will mean for Denbury and our future. Penn Virginia and  Denbury bring great assets and talents to the combined company, and we have much that we can learn  from each other and many ways in which we can collaborate to make the whole much greater than the  sum of the parts. I look forward to welcoming Penn Virginia’s employees to the Denbury team.  I thank each of you for all that you have done to put us in a position to take this important next step for  the Company, and I look forward to providing more details with you at the town hall and thereafter as  the transaction moves forward.  Sincerely,   Chris
