          included in the calculation of RAM's aggregate indebtedness for
          certain calculations and purposes under the Merger Agreement.

ITEM 7.01 REGULATION FD DISCLOSURE

     The October 2005 8-K provided certain information, as of June 30, 2005,
regarding RAM and its operations, including certain information relating to
RAM's oil, natural gas and natural gas liquids reserves. The following is an
update, as of September 30, 2005, to that information.

GENERAL
-------

     At September 30, 2005, RAM's estimated net proved reserves were 19.7
million barrels of oil equivalent, or Boe, of which approximately 60% were crude
oil, 29% were natural gas, and 11% were natural gas liquids, or NGLs, with a
present value of future net revenue before applicable income taxes, discounted
at 10%, or PV-10 Value, of approximately $445 million, based on prices RAM was
receiving as of September 30, 2005, which were $63.62 per barrel, or Bbl, of
oil, $39.21 per Bbl of NGLs, and $12.70 per thousand cubic feet, or Mcf, of
natural gas. At that date, RAM's proved developed reserves comprised 71% of its
total reserves and the estimated reserve life for RAM's total proved reserves
was approximately 14 years. RAM owns interests in approximately 2,900 wells and
operates approximately 1,900 of these wells. The wells RAM operates represented
approximately 89% of its PV-10 Value as of September 30, 2005. In addition, RAM
has positioned itself for participation in two emerging resource plays: (1) the
on-going Barnett Shale play located in Jack and Wise Counties, Texas, where RAM
owns interests in approximately 27,700 gross acres (6,800 net acres) and (2) an
exploratory Barnett and Woodford Shale play located in Reeves County, Texas,
where RAM owns interests in approximately 70,000 gross acres (11,000 net acres).
RAM also owns interests in various gathering systems and a natural gas
processing plant that serves its producing properties.

     During 2005, RAM expects to drill or participate in the drilling of 67
total wells, 64 of which will be development wells and three of which will be
exploratory wells. Through September 30, 2005, RAM has participated in the
drilling of 48 wells and completed recompletions in 18 of its existing wells.
From 1997 through December 31, 2004, RAM's reserve replacement ratio, through
discoveries, extensions, revisions and acquisitions, but excluding dispositions,
was 324%. From 1989 through September 30, 2005, RAM drilled or participated in
the drilling of 446 oil and natural gas wells with a 92% success rate.

     For its fiscal year ended December 31, 2004, RAM reported total oil and gas
sales of $17.7 million. For the nine months ended September 30, 2005, RAM
reported total oil and gas sales of $48.3 million.

OIL AND GAS PROPERTIES
----------------------

     RAM's principal fields and core operating areas are as follows:

     o    Electra/Burkburnett Area, Wichita and Wilbarger Counties, Texas; 

     o    Egan Field, Acadia Parish, Louisiana;

     o    Boonsville Area, Jack and Wise Counties, Texas;

     o    Barnett Shale, Jack and Wise Counties, Texas; and

     o    Vinegarone Field, Val Verde County, Texas.

     ELECTRA/BURKBURNETT AREA

     RAM's properties in the Electra/Burkburnett Area of North Texas include 26
leases covering 12,190 gross acres. As of September 30, 2005, RAM owned
interests in approximately 1,600 wells in the Electra/Burkburnett Area, of which
508 were active producing wells and 210 were active injection wells.



                                       5


     RAM, together with its recently acquired subsidiary, RWG, drilled more than
50 wells in the Electra/Burkburnett Area from November 1, 2004 through
September, 30, 2005, and another 209 drilling locations are currently booked as
proved undeveloped.

     RAM estimates the average infill well remaining to be drilled in the
Electra/Burkburnett Area should have ultimate recoverable reserves of
approximately 22,000 Bbls of oil. Drilling and completion costs are estimated to
average approximately $135,000 per well.

     On April 1, 2005, RAM purchased a drilling rig specifically for the purpose
of facilitating its ongoing drilling program in the Electra/Burkburnett Area.
RAM is currently drilling an average of six wells per month.

     RAM sells the crude oil produced from its Electra/Burkburnett Area
properties to Shell Trading (US) Company. For the month of September 2005, the
sale price was $63.62 per Bbl of oil.

     During the nine months ended September 30, 2005, the aggregate net
production attributable to RAM's interest in its Electra/Burkburnett properties
was 492,798 Bbls of oil and 37,433 Bbls of NGLs, or 530,231 Boe, and average
daily production for the period was 1,948 Bbls of oil per day and 148 Bbls of
NGLs per day, or 2,096 Boe per day.

     During September 2005, aggregate net production attributable to RAM's
interest in its Electra/Burkburnett properties was 53,045 Bbls of oil and 4,109
Bbls of NGLs, or 57,154 Boe, and the average daily production was 1,768 Bbls of
oil per day and 137 Bbls or NGLs per day, or 1,905 Boe per day. Production from
RAM's Electra/Burkburnett Area properties during the month of September 2005 was
adversely impacted by Hurricane Rita.

     EGAN FIELD

     RAM's Egan Field, located in Acadia Parish, Louisiana, covers an area of
approximately 4,400 acres. Over the past 60 years, more than 90 wells have been
drilled in the field. Current production from the Egan Field is obtained
primarily at depths ranging from 9,000 feet to 12,400 feet.

     Over the past five years, RAM has undertaken a recompletion program in the
Egan Field, conducting successful operations in 12 wells, and has identified
more than 10 additional recompletion opportunities in existing wellbores.

     RAM owns or has licensed over 41 miles of 2-D and 3-D seismic covering its
Egan Field properties. As a result of recent and ongoing analysis of this data,
RAM expects to have a new inventory of additional drilling and recompletion
prospects on its Egan Field properties for exploitation and development over the
next several years.

     RAM owns interest in approximately 4,367 gross (2,633 net) leasehold acres
and 11 producing wells in the Egan Field, and is the operator of all such wells.



                                       6


     For the nine months ended September 30, 2005, the aggregate net production
attributable to RAM's interest in the Egan Field properties was 15,529 Bbls of
oil and 378 MMcf of natural gas, or 78,612 Boe, and average daily production for
the period was 311 Boe per day.

     During September 2005, aggregate net production attributable to RAM's
interest in its Egan Field properties was 1,273 Bbls of oil and 30 MMcf of
natural gas, or 6,271 Boe, and RAM's daily production for the period was 42 Bbls
of oil per day and 1,000 Mcf of natural gas per day, or 209 Boe per day.
Production from RAM's Egan Field properties during the month of September 2005
was adversely impacted by Hurricanes Katrina and Rita.

     BOONSVILLE AREA

     The Boonsville Area is located in the Fort Worth Basin of North Central
Texas in Jack and Wise Counties, and includes RAM's Barnett Shale rights. RAM's
leasehold in the area covers approximately 9,950 gross acres lying within the
much larger Boonsville Field, which includes several hundred thousand acres.

     RAM's properties in Jack and Wise Counties are comprised of two discrete
subsets: the shallow gas zones and the Barnett Shale acreage. A considerable
portion of RAM's leasehold in the area is segregated with respect to rights
above and below the Marble Falls formation, a prominent geologic marker in the
area. RAM's substantially undeveloped Barnett Shale acreage (which lies below
the Marble Falls) is a distinct property requiring drilling, completion and
production techniques dissimilar from the shallow gas producing zones.
Accordingly, RAM treats its Barnett Shale acreage as a separate major property.

     RAM's oil and gas production in the Boonsville Area is derived principally
from sands found at depths ranging from 3,800 feet to 6,100 feet. RAM owns
working interests in 84 wells producing from these shallow gas zones and
operates all but one of such wells.

     RAM owns and operates an extensive gas gathering system in the field which
gathers gas solely from RAM's wells. The gas is compressed in the field through
compression facilities also owned by RAM, and then is delivered into a larger
system operated by Dynegy for delivery to the Dynegy-owned Chico gas processing
plant, where the natural gas is processed for the extraction of NGLs. RAM
currently receives 80% of both the residue gas and the NGLs attributable to its
share of delivered volumes.

     RAM has not drilled any wells in the Boonsville Area since its acquisition
of WG Energy Holdings in December 2004. Currently, there are 22 drilling
locations identified as proved undeveloped locations.

     During the nine months ended September 30, 2005, the aggregate net
production attributable to RAM's working interests in the Boonsville Area
properties (above the Marble Falls) was 18,846 Bbls of oil, 434 MMcf of natural
gas and 96,998 Bbls of NGLs, or 188,230 Boe, and average daily production for
the period was 74 Bbls of oil per day, 1,717 Mcf of natural gas per day and 383
Bbls of NGLs, or 744 Boe per day.

     During September 2005, aggregate net production attributable to RAM's
interest in the Boonsville shallow gas properties was 1,252 Bbls of oil, 35,891
Mcf of natural gas, and 8,376 


                                       7


Bbls of NGLs, and the average daily production for the period was 42 Bbls of
oil, 1,199 Mcf of natural gas and 279 Bbls of NGLs or 521 Boe per day.
Production from RAM's Boonsville Area properties during the month of September
2005 was adversely impacted by Hurricane Rita.

     BARNETT SHALE ACREAGE

     RAM owns leases covering approximately 27,700 gross (6,800 net) acres of
Barnett Shale rights, all of which are held by production from wells completed
in the shallow gas zones. The Barnett Shale currently is the largest natural gas
play in Texas. RAM's Barnett Shale acreage lies in the Boonsville Area of Jack
and Wise Counties, Texas, below the Marble Falls geologic marker at depths
ranging from 6,500 feet to 8,500 feet and is, for the most part, undeveloped.

     The Barnett Shale area is an emerging resource play with the potential to
become a multi-well, long-lived gas project with substantial exploitation
opportunity and is believed to be one of the most promising new natural gas
plays in the United States. The most productive wells in the Barnett Shale play
are wells that have been drilled horizontally. The average cost of drilling and
completing a horizontal well to the Barnett Shale is approximately $1.75 to $2.2
million.

     RAM is a party to two separate agreements covering its acreage position in
the Barnett Shale:

     o    Approximately 3,500 gross acres are subject to a Participation
          Agreement with Chief Oil & Gas, Inc., with RAM having the right to
          participate with a 36% working interest in each well proposed to be
          drilled on the contract area. The agreement is on a "drill-to-earn"
          basis and includes a continuous drilling obligation, requiring Chief
          to commence a new well within 120 days after the filing of a
          completion report on the preceding well, failing which Chief's right
          to earn under the Participation Agreement will terminate. To date
          Chief has drilled and completed three commercially productive
          horizontal wells, with a fourth well now being completed, and a fifth
          well proposed for drilling during the last quarter of this year.

     o    RAM's remaining Barnett Shale acreage (approximately 24,000 gross
          acres) is committed to an agreement with EOG Resources, Inc. RAM has a
          23.9% working interest in this acreage block. Currently, RAM and its
          partners are acquiring and interpreting 3D seismic data with the
          expectation that a number of locations will be identified for drilling
          commencing in 2006.

     Although the Barnett Shale play has not yet made a substantial contribution
to RAM's daily production, RAM believes that there are approximately 127
probable drilling locations on RAM's Barnett Shale acreage, with 108 of those
probable wells to be located on leasehold subject to the EOG agreement and 19 on
the Chief acreage block.

     During the nine months ended September 30, 2005, the aggregate net
production attributable to RAM's interest in the currently producing Barnett
Shale wells was 2,971 Bbls of oil and 182 MMcf of natural gas, and average daily
production for the period was 11 Bbls of oil and 719 Mcf of natural gas per day,
or 131 Boe per day.

                                       8


     During September 2005, the aggregate net production attributable to RAM's
interest in the Barnett Shale properties was 222 Bbls of oil and 21 MMcf of
natural gas, and the average daily production for the period was 7 Bbls of oil
per day and 705 Mcf of natural gas per day, or 125 Boe per day.

     VINEGARONE FIELD

     The Vinegarone Field is located in Val Verde County, Texas, which is in the
Big Bend region of South Texas. RAM owns working interests in seven producing
wells in the field, none of which are operated by RAM.

     Production from Vinegarone Field is obtained primarily from three distinct
horizons at depths ranging from 9,100 feet to 10,100 feet. RAM owns interests in
6,686 gross (1,682 net) leasehold acres in the Vinegarone Field.

     During 2004, RAM participated in the drilling of four new wells in the
Vinegarone Field, three of which were successfully completed. RAM has identified
seven proved undeveloped locations in the field and expects to continue its
development of the field over the next three years.

     For the nine months ended September 30, 2005, the aggregate net production
attributable to RAM's interest in the Vinegarone Field properties was 333 MMcf
of natural gas, and the average daily production for the period was 1,317 Mcf of
natural gas per day, or 219 Boe per day.

     During September 2005, the aggregate net production attributable to RAM's
interest in the Vinegarone Field was 28 MMcf of natural gas , and the average
daily production for the period was 948 Mcf of natural gas, or 158 Boe per day.

     OTHER PROPERTIES

     In addition to its principal fields and core operating areas, RAM also owns
interests in other properties located in Texas, Oklahoma, Mississippi,
Louisiana, Kansas, New Mexico, Wyoming, Arkansas and offshore California.

     RAM owns a significant number of properties scattered throughout the
principal producing basins in Oklahoma. In addition, RAM also owns an interest
in two exploration prospects in Oklahoma and is actively seeking other
exploration opportunities throughout its core areas.

     In Texas, in addition to the Electra/Burkburnett and Boonsville Area
properties, RAM owns miscellaneous operated and non-operated interests in 45
producing wells across the state, from the Panhandle down through the Permian
Basin to South Texas, and eastward to Louisiana. It also owns a substantial
position in an exploratory project located in Reeves County, Texas where it owns
interests in approximately 70,000 gross acres and 11,000 net acres. Virtually
all of RAM's leasehold interest in Reeves County is subject to farmout
agreements with either J. Cleo Thompson, et al., or 777 Energy, LP (successor to
Alpine, Inc.). The 777 Energy farmout covers roughly half of RAM's gross acreage
position and has resulted in the drilling of two 


                                       9


Barnett Shale wells, one vertically and one horizontally, with the horizontal
well now awaiting a completion attempt. The remaining acreage is subject to a
farmout agreement with J. Cleo Thompson, et al., which requires the acquisition
of 10 square miles of 3D seismic preparatory to the drilling of a well on or
before March 1, 2006 to a depth sufficient to test the Woodford Shale. Both
farmout agreements allow the farmee to earn an interest in certain of RAM's
leases by drilling the initial obligatory wells and then continue to earn
interests by drilling subsequent wells within 90 to 180 days after commencement
of the immediately preceding well. RAM has the right to participate for one-half
of its interest in the wells drilled subsequent to the initial earning wells
under each farmout agreement.

OIL AND NATURAL GAS RESERVES
----------------------------

     The following table summarizes the estimates of RAM's historical net proved
reserves and the related present values of such reserves at the dates shown. The
reserve and present value data for RAM's oil and natural gas properties as of
September 30, 2005, were prepared by employees of RAM. The data for December 31,
2004 were prepared by the independent petroleum engineering firms of Williamson
Petroleum Consultants and Forrest A. Garb & Associates. The data for December
31, 2003 and 2002 were prepared by the independent petroleum engineering firm of
Forrest A. Garb & Associates. In the following table, PV-10 Value represents the
present value of estimated future net revenues before income tax discounted at
10%, using prices in effect at the end of the respective periods presented and
excluding the effects of hedging activities. Estimates of RAM's proved reserves
and future net revenues are made using published period-end spot oil and natural
gas sales prices and are held constant throughout the life of the properties.
The prices used in calculating PV-10 Value as of September 30, 2005 were $63.62
per Bbl of oil, $39.21 per Bbl of NGLs and $12.70 per Mcf of natural gas. The
prices at which RAM sells natural gas typically are determined on the first day
of each month for the entire month. In the following table, "proved reserves"
include proved developed reserves and proved undeveloped reserves. The PV-10
values set forth in the table do not include any of RAM's undeveloped Barnett
Shale acreage.

     Estimated quantities of proved reserves and future net revenues therefrom
are affected by oil and natural gas prices, which have fluctuated widely in
recent years. There are numerous uncertainties inherent in estimating oil and
natural gas reserves and their values, including many factors beyond the control
of the producer. The reserve data set forth in this report represents only
estimates. Reservoir engineering is a subjective process of estimating
underground accumulations of oil and natural gas that cannot be measured in an
exact manner. The accuracy of any reserve estimate is a function of the quality
of available data and of engineering and geological interpretation and judgment.
As a result, estimates of different engineers, including those used by RAM, may
vary. In addition, estimates of reserves are subject to revisions based upon
actual production, results of future development and exploration activities,
prevailing oil and natural gas prices, operating costs and other factors, which
revisions may be material. The PV-10 Value of RAM's proved oil and natural gas
reserves does not necessarily represent the current or fair market value of such
proved reserves, and the 10% discount factor may not reflect current interest
rates, RAM's cost of capital or any risks associated with the development and
production of its proved oil and natural gas reserves.

     In general, the volume of production from oil and natural gas properties
declines as reserves are depleted. Except to the extent RAM acquires properties
containing proved reserves or conducts successful exploitation and development
activities, RAM's proved reserves will decline as reserves are produced. RAM's
future oil and natural gas production is, therefore, highly dependent upon its
level of success in finding or acquiring additional reserves.

OIL AND NATURAL GAS MARKETING AND HEDGING
-----------------------------------------

     RAM's oil and natural gas production is sold primarily under market
sensitive or spot price contracts. During the nine months ended September 30,
2005, three customers accounted for approximately 75% of RAM's sales of oil and
natural gas. RAM believes there are numerous other companies available to
purchase RAM's oil and natural gas, and that the loss of any or all of these
purchasers would not materially affect its ability to sell oil and natural gas.
However, if the natural gas gathering and processing system and plant located in
the Boonsville Area that is currently owned by RAM's second largest customer
were to cease operations, whether for mechanical, financial or other reasons,
such cessation could materially and adversely affect RAM's cash flow from
operations on a temporary basis. RAM has no reason to believe that any such
cessation is likely to occur.

     To reduce exposure to fluctuations in oil and natural gas prices and to
achieve more predictable cash flow, RAM periodically utilizes various hedging
strategies to manage the price received for a portion of its future natural gas
and oil production. RAM has not established hedges in excess of its expected
production. These strategies customarily involve the purchase of put options to
provide a price floor for its production, put/call collars that establish both a
floor and a ceiling price to provide price certainty within a fixed range,
put/call/call collars that establish a secondary floor above the put/call collar
ceiling, and forward sale contracts for specified monthly volumes at prices
determined with reference to the natural gas futures market or swap arrangements
that establish an index-related price above which RAM pays the hedging partner
and below which RAM is paid by the hedging partner. These contracts allow RAM to
predict with greater certainty the effective oil and natural gas prices to be
received for its production and benefit RAM when market prices are less than the
strike prices or fixed prices 


                                       11


under its hedging contracts. However, RAM will not benefit from market prices
that are higher than the strike or fixed prices in these contracts for its
hedged production.

     RAM's hedge positions at September 30, 2005 are shown in the following

     RAM's hedging contracts for oil continue through December 2007, and its
contracts for natural gas continue through March 2007. Natural gas floors and
ceilings for 2007 are for January through March and natural gas secondary floors
for 2006 are for April through October. For the three months ended September 30,
2005, RAM produced 2,160 Bbls of oil per day, 6,441 Mcf of natural gas per day,
and 435 Bbls of NGLs per day.

NON-GAAP FINANCIAL MEASURES
---------------------------

     Included in the slideshow annexed to this 8-K Amendment are calculations of
RAM's EBITDA for various periods. RAM's EBITDA is determined by adding the
following items to net income (loss): net interest expense, provision for income
taxes, depreciation and amortization, unrealized gain or loss from derivatives,
gain on disposal of assets, loss from discontinued operations, and cumulative
effect of change in accounting principle. A reconciliation of RAM's EBITDA to
net income (loss) is presented below.

     RAM's EBITDA is being presented in the slideshow because we believe EBITDA
provides useful information regarding RAM's continuing operating results. RAM
relies on EBITDA as a primary measure to review and assess the operating
performance of its company and its management team. RAM also reviews EBITDA to
compare its current operating results with corresponding periods and with the
operating results of other companies in its industry. RAM also utilizes EBITDA
as an assessment of its overall liquidity and its ability to meet its debt
service obligations.

     RAM believes that EBITDA is useful to investors to provide disclosures of
its operating results on the same basis as that used by management. RAM also
believes that EBITDA can assist investors in comparing RAM's performance to that
of other companies on a consistent basis without regard to certain items, which
do not directly affect its ongoing operating performance or cash flows. EBITDA
has limitations as an analytical tool, and you should not consider it in
isolation or as a substitute for net income, cash flows from operating
activities and other consolidated income or cash flows statement data prepared
in accordance with accounting 


                                       12


principles generally accepted in the United States. Because of these
limitations, EBITDA should not be considered a measure of discretionary cash
available to RAM to invest in the growth of its business.
