Exhibit 99.1


                           IMPORTANT NOTICE REGARDING
                  THE MERIDIAN RESOURCE CORPORATION 401(k) PLAN

                    BLACKOUT PERIOD AND YOUR RIGHTS TO TRADE
    THE MERIDIAN RESOURCE CORPORATION COMMON STOCK DURING THE BLACKOUT PERIOD

To:      The Meridian Resource Corporation Directors and Executive Officers

From:    Lloyd DeLano

Date:    June 24, 2005

         The purpose of this notice is to inform you that The Meridian Resource
Corporation 401(k) Plan (the "Plan") will be entering a blackout period on
Monday, July 25, 2005, at approximately 2:00 p.m., Central Daylight Savings
Time, due to a trustee and recordkeeper conversion from Sterling Trust Company
to Retirement Services, Inc. During the blackout period, participants in the
Plan will not be able to direct or diversify investments in their individual
accounts or obtain a distribution. This includes participants' investments in
The Meridian Resource Corporation Common Stock through a brokerage account under
the Plan.

         The Securities and Exchange Commission ("SEC") has implemented rules
under the Sarbanes-Oxley Act of 2002 (P.L. 107-204) which apply to 401(k) plan
blackout periods. Because you are a director or executive officer of The
Meridian Resource Corporation (the "Company"), please be aware that the blackout
period for the Plan has a direct impact on your ability to trade the Company's
Common Stock. A copy of the blackout notice provided to the affected
participants of the Plan is attached to this notice.

         The SEC rules provide prohibitions on:

         o  an acquisition of issuer equity securities by a director or
            executive officer during a blackout period if the acquisition is in
            connection with his or her service or employment as a director or
            executive officer; and

         o  a disposition of issuer equity securities by a director or executive
            officer during a blackout period if the disposition involves issuer
            equity securities acquired in connection with his or her service or
            employment as a director or executive officer.

         Equity securities acquired in connection with the individual's service
as a director or officer are subject to the restriction, including securities
acquired before the Sarbanes-Oxley Act was passed or before the Company went
public. You should note that there is a presumption that any securities sold
during a blackout period are not exempt from the rule (that is, the individual
corporate insider bears the burden of proving that the securities were not
"acquired in connection with service or employment").

         The SEC rules exempt certain transactions from the trading restriction.
Some of these exemptions are as follows:

         o  regularly scheduled purchases or sales of employer securities
            pursuant to an automatic election, which satisfy SEC Rule 10b5-1;


         o  purchases or sales of company stock, other than in a discretionary
            transaction, under an employee stock purchase plan or a qualified
            401(k) retirement plan in the normal course of on-going employee
            deferrals;

         o  increases or decreases in equity holdings resulting from a stock
            split, stock dividend or pro rata rights distribution;

         o  grant of an option or other equity compensation under certain plans;
            and

         o  acquisition or disposition of equity securities involving a bona
            fide gift.

KEY DATES:

401(k) Blackout Begins:  Monday, July 25, 2005

401(k) Blackout Expected to End:  Wednesday, August 17, 2005

         During the period from July 25, 2005, through August 17, 2005, you
should contact Liz Hensley or Rachel Martinez at (281) 597-7000 to determine
whether the blackout period has ended.

         Violations of the insider trading prohibition will allow an issuer or a
security holder acting on behalf of an issuer to bring an action to recover the
profits realized by the director or executive officer. In addition, the SEC may
bring an action, including civil injunction proceedings, cease-and-desist
actions, civil penalties and all other remedies available to the SEC under the
Exchange Act, including, in some cases, criminal penalties.

         Please be aware that on June 24, 2005, a notice will be mailed to all
current and former participants in the Plan to inform them of the blackout
period. This meets the 30-day Sarbanes-Oxley advance notice requirement for all
plan participants.

         While we anticipate a smooth transition, you will be notified in the
unlikely event that an extension of the blackout period is needed. If you have
any questions concerning this notice, you should contact Liz Hensley or Rachel
Martinez at (281) 597-7000.
