                          RIDGEWOOD ENERGY K FUND, LLC

                     NOTES TO UNAUDITED FINANCIAL STATEMENTS

1. Organization and Purpose

The Ridgewood Energy K Fund, LLC ("Fund"), a Delaware limited liability company,
was formed on March 1, 2004 and operates pursuant to a limited liability company
agreement ("Agreement") dated as of April 1, 2004 by and among Ridgewood Energy
Corporation ("Manager"), and the shareholders of the Fund.

The Fund was organized to acquire, drill, construct and develop natural gas and
oil properties located in the United States offshore waters of Texas and
Louisiana in the Gulf of Mexico.

2. Summary of Significant Accounting Policies

     Basis of presentation

These interim financial statements have been prepared by the Fund's management,
without audit, in accordance with accounting principles generally accepted in
the United States of America and in the opinion of management, contain all
adjustments (consisting of only normal recurring adjustments) necessary to
present fairly the Fund's financial position, results of operations and cash
flows for the periods presented. Certain information and note disclosures
normally included in annual financial statements prepared in accordance with
accounting principles generally accepted in the United State of America have
been omitted in these interim financial statements. The results of operations,
financial position, and cash flows for the periods presented herein are not
necessarily indicative of future financial results. These interim financial
statements should be read in conjunction with the annual financial statements
and the notes thereto for the period ended December 31, 2004 included in the
Fund's Registration Statement on Form 10 filed with the SEC, as it may be
amended from time to time. The Fund had no business operations or activities
prior to April 22, 2004.

     Use of Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities as of the date
of the financial statements and the reported amounts of revenues and expenses
during the reporting period. On an ongoing basis, the Manager reviews its
estimates, including those related to environmental liabilities, impairment
allowance and determination of proved reserves. Actual results may differ from
those estimates.

     Oil and gas properties

Investments in oil and gas properties were operated by unaffiliated entities
("Operators") who are responsible for drilling, administering and producing
activities for leases jointly owned by working interest owners pursuant to the
terms of the applicable Operating Agreements. The Fund's portion of exploration,
drilling, operating and capital equipment expenditures relating to the wells are
advanced and billed by Operators through authorization for expenditures.

The successful efforts method of accounting for oil and gas producing activities
is followed. Costs to acquire mineral interests in oil and gas properties, drill
and equip exploratory wells to find proved reserves, drill and equip
developmental wells and related asset retirement costs are capitalized. Costs to
drill exploratory wells that do not find proved reserves, geological and
geophysical costs and costs of carrying and retaining unproved properties are
expensed. There were $755,305 of dry hole costs in the second quarter. The dry
hole cost for the six months ended June 30, 2005 totaled $1,240,854.

Unproved oil and gas properties that are individually significant are
periodically assessed for impairment of value, and a loss recognized in the
event of impairment by providing an impairment allowance. Capitalized
acquisition costs of producing oil and gas properties after recognizing
estimated salvage values are depreciated and depleted by the unit-of-production
method.

     Revenue Recognition

Oil and gas sales are recognized when delivery is made by the Operator to the
purchaser and title transferred, i.e., production has been delivered to a
pipeline or transport vehicle.

Interest income is recognized when earned.

                                       7
<PAGE>


     Assets Retirement Obligations

For a substantial portion of the assets, there are obligations to perform
removal and remediation activities when the asset is retired. However, the fair
value of the asset retirement obligations cannot be reasonably estimated, since
the retirement dates are indeterminate. Asset retirement obligations will be
recognized in the period the retirement dates are determined.

     Impairment of Long-Lived Assets

In accordance with the provisions of SFAS No. 144, Accounting for the Impairment
of Long-Lived Assets, the long-lived assets, such as oil and gas properties are
evaluated when events or changes in circumstances indicate that the carrying
value of such assets may not be recoverable. The determination of whether
impairment has occurred is made by comparing the carrying future value to the
estimated future discounted cash flows attributable to that asset. The
impairment loss recognized is the excess of the carrying value over the future
discounted cash flows attributable to the asset or the estimated fair value of
the asset.

     Depletion and Amortization

Acquisition costs of proved properties are depleted (or amortized) on the basis
of units of production and total estimated units of proved, developed and
undeveloped, reserves. Other capitalized costs on proved properties are depleted
(or amortized) on the basis of units of production and total estimated units of
proved developed reserves. For the three months ended June 30, 2005, depletion
and amortization totaled $829,390.

     Income Taxes

No provision is made for income taxes in the financial statements as the income
or losses are passed through and included in the tax returns of the individual
shareholders.

     Cash and cash equivalents

All highly liquid investments with maturities when purchased of three months or
less are considered as cash and cash equivalents. At times, bank deposits may be
in excess of federal insured limits.

     Income and Expense Allocation

Profits and losses are to be allocated 85 % to shareholders in proportion to
their relative capital contributions and 15% to the Manager, except for items of
expense, loss, deduction and credit attributable to the expenditure of
shareholders' capital contributions which are allocated 99% to shareholders and
1% to the Manager.

3. Transactions with Manager

A management agreement provides that the Manager render management,
administrative and advisory services. For such services, the Manager receives an
annual management fee, payable monthly, of 2.5% of total capital contributions
and receives 15% of distributions made out of operating income by the Fund. For
the three months ended June 30, 2005 and 2004, a management fee of $442,875 and
$76,375, respectively, was paid. For the six months ended June 30, 2005 and
2004, a management fee of $885,750 and $76,375, respectively, was paid. The Fund
made its first distribution in June 2005. Of this distribution, the 15% paid to
the Manager was $32,892.

From time to time, short-term payables and receivables, which do not bear
interest, arise from transactions with affiliates in the ordinary course of
business.

The Fund co-invests with affiliated funds managed by the Manager to acquire and
develop oil and gas projects.

4. Commitment and Contingencies

     Environmental Considerations

The exploration for and development of oil and gas involves the extraction,
production and transportation of materials which, under certain conditions, can
be hazardous or cause environmental pollution problems. The Manager and the
Operators are continually taking action they believe appropriate to satisfy
applicable federal, state and local environmental regulations and do not
currently anticipate that compliance with federal, state and local environmental
regulations will have a material adverse effect upon capital expenditures,

                                       8
<PAGE>

earnings or the competitive position in the oil and gas industry. However, due
to the significant public and governmental interest in environmental matters
related to those activities, the Manager cannot predict the effects of possible
future legislation, rule changes, or governmental or private claims.

     Salvage Fund

Pursuant to the Fund's Operating Agreement, a portion of monthly net revenue
will be reserved in Salvage Funds, which will be separated into interest bearing
accounts, until a Salvage Fund contains an amount equal to the anticipated cost
of dismantling and removing production wells and platforms, in accordance with
applicable federal and state laws and regulations. Currently, the fair value of
the asset retirement obligations cannot be reasonably estimated, as the
retirement dates are indeterminate.

     Insurance Coverage

The Fund is subject to all risks inherent in the exploration for and development
of oil and gas. Insurance coverage as is customary for entities engaged in
similar operations is maintained, but losses may occur from uninsurable risks or
amounts in excess of existing insurance coverage. The occurrence of an event
which is not insured or not fully insured could have an adverse impact upon
earnings and financial position.

Item 2.  Management's Discussion and Analysis of Financial Condition and Results
of Operations

            Cautionary Statement Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q, including all documents incorporated by
reference, includes "forward-looking" statements within the meaning of Section
27A of the Securities Act of 1933, as amended (the "Securities Act") and Section
21E of the Securities Exchange Act of 1934, as amended, and the Private
Securities Litigation Reform Act of 1995, and the "safe harbor" provisions
thereof. These forward-looking statements are usually accompanied by the words
"anticipates," "believes," "plan," "seek," "expects," "intends," "estimates,"
"projects," "will likely result," "will continue," "future" and similar terms
and expressions. The forward-looking statements in this Quarterly Report on Form
10-Q reflect our current views with respect to future events and financial
performance. These forward-looking statements are subject to certain risks and
uncertainties, including, among other things, the high-risk nature of natural
gas exploratory operations, the fact that our drilling activities are managed by
third parties, the volatility of oil and gas prices and extraction, and those
other risks and uncertainties discussed in the Fund's Registration Statement on
Form 10 filed with the Securities and Exchange Commission that could cause
actual results to differ materially from historical results or those
anticipated. In light of these risks and uncertainties, there can be no
assurance that the forward-looking information contained in this Quarterly
Report on Form 10-Q will in fact occur or prove to be accurate. Readers should
not place undue reliance on the forward-looking statements contained herein,
which speak only as of today's date. We undertake no obligation to publicly
revise these forward-looking statements to reflect events or circumstances that
may arise after today. All subsequent written or oral forward-looking statements
attributable to us or persons acting on our behalf are expressly qualified in
their entirety by this section.

Critical Accounting Policies and Estimates

The following discussion and analysis of our financial condition and operating
results are based on our financial statements. The preparation of this Quarterly
Report on Form 10-Q requires us to make estimates and assumptions that affect
the reported amount of assets and liabilities, disclosure of contingent assets
and liabilities at the date of our financial statements, and the reported amount
of revenue and expenses during the reporting period. Actual results may differ
from those estimates and assumptions. See "Notes to Unaudited Financial
Statements" in Part I of this Form 10-Q for a presentation of the Fund's
critical accounting principles.

Overview

The Fund commenced active operations on April 22, 2004 when it began its private
offering of shares. During 2004, the Fund raised capital by selling 480.705
shares for $70,859,719. The Fund's primary business is obtaining economic
interest in the exploration and development of oil and gas projects. The
business activities are managed by Ridgewood Energy Corporation, the Manager.
The Fund does not directly explore for, or operate, any projects. The Manager,
on behalf of the Fund, enters into operating agreements with third party
operators for the exploration and possible development of projects. These
third-party operators manage all day-to-day activities of projects, determine
expenditures and report their activities to the Manager.

Results of Operations

We have one producing property that began production in October 2004. As a
result, other than interest income of $26,479 for the three months ended and the

                                       9
<PAGE>

period ended June 30, 2004, there was no other revenue. For the three months
ended June 30, 2005, the Fund's revenue increased $718,811 which was made up of
gas sales totaling $491,957, oil sales of $149,015 and interest income of
$77,839. For the period ended June 30, 2005, the Funds revenue totaled
$1,203,718 which reflected gas sales totaling $881,516, oil sales of $181,734
and interest income of $140,468.

For the three months ended June 30, 2005, there were well operating expenses of
$151,642 and depletion and amortization expenses of $829,390. For the period
ended June 30, 2005, the well operating expenses totaled $216,925 and the
depletion and amortization totaled $1,216,731. Such expenses did not exist for
the three months ended or the period ended June 30, 2004 because these expenses
are only incurred once a well starts producing.

The Fund also had dry hole expense of $775,305 for the three months ended June
30, 2005 and $1,240,854 for the period ended June 30, 2005. There is no similar
expense for the same time periods in June 2004 because the Fund had yet to
commit to or drill a well.

For the three months ended June 30, 2005, there was no investment fee expense
because the Fund closed in August, 2004 and all investment fees were paid in
2004. For the three months ended and the period ended June 30, 2004, the fund
was still raising capital and as a result, investment fee expense was the
largest expense totaling $2,639,905.

Management fees are 2.5% of the total capital contributions. Management fees for
the three months ended and the period ended June 30, 2005 were $442,875 and
$885,750 respectively. For the three months ended and the period ended June 30,
2004 management fees totaled $76,375. The Fund started raising capital on April
1, 2004. The management fee is based on capital contributed on the last day of
the month for the month prior. As a result, until the Fund is closed, the
management fee changes from month to month based on commitments. The Fund
continued its offering through August 2004, therefore, the management fees were
calculated based on monthly commitments. Once the Fund closed, the annual
management fee remains constant at $1,771,500 or $442,875 quarterly.

For the three months and the period ended June 30, 2005, insurance expense
totaled $192,369 and $205,689 respectively. Well Control insurance costs are
expensed in the quarter a well spuds (starts drilling). As a result, the timing
of the expense will fluctuate based on when a well will be drilled. For the
three months and the period ended June 30, 2005 there was no well control
insurance because the Fund had yet to drill a well.

Liquidity and Capital Resources

Cash and cash equivalents decreased by $7.9 million during the first six months
of 2005 from $18.9 million at December 31, 2004 to $11 million at June 30, 2005.

During the three months ended June 30, 2005 and the period ended June 30, 2005,
we purchased oil and gas properties totaling $299,373 and $3,022,654,
respectively, relating to projects. The balance of cash was used to pay
management fees to our Fund Manager as well as other Fund expenses which was
offset by cash generated from oil and gas production.

Through June 30 2005, the Fund has made one distribution to its shareholders.
The total distributions made to shareholders in June 2005 totaled $186,388. The
Manager may distribute available cash from operations which includes cash
received by the Fund from the operation of the business (not including cash flow
from dispositions and investor capital contributions), less operating expenses
and other cash expenditures and less reserves for operating expenses, plug and
abandonment costs and certain other actual and contingent liabilities.
Distributions may include funds derived from the release of cash from operating
reserves. Further, distributions will be made from operating cash flows rather
than net income, or from available cash reserves in some instances. For purposes
of generally accepted accounting principles, amounts of distributions in excess
of accounting income may be considered to be capital in nature.

Future Trends

Revenue to the Fund is sensitive to changes in price received for natural gas
production. Prevailing market prices fluctuate in response to many factors that
are outside of our control such as the supply and demand for natural gas.
Availability of alternative fuels also impacts the supply while other economic
factors may impact the demand.

High natural gas prices have resulted in a strong demand for and a tight supply
of drilling rigs necessary to drill new wells. The increased cost in daily rig
rates could have a negative impact on the return to investors in the Fund. The
shortage of drilling rigs could delay the employment of capital to such projects
and thus delay revenue from operations.

Wells drilled may not have commercially productive natural gas reservoirs. In
such an event, the Funds' revenue, future results of operations and financial
condition would be adversely impacted.

Estimated Capital Expenditures

The Fund has entered into multiple Offshore Operating Agreements for the
drilling and development of its investment properties. The estimated capital
expenditures associated with these agreements can vary depending on the stage of
development on a property-by-property basis. As of June 30, 2005, such estimated
capital expenditures total $7 million, all of which is expected to be paid
within the following 12 months.

The Manager receives an annual management fee of 2.5% of total capital
contributions for administrative and advisory services as well as reimbursement
of expenses. As additional compensation for its duties as Manager, it will also
receive up to a maximum 15% of distributions from the Fund. In June 2005, the
Manager was paid a distribution in the amount of $32,892.

i)            Assumes the wells are commercially successful. If one or more of
              the wells is dry, the development capital will be reallocated to
              one or more new unspecified projects.
ii)           Although the management fee and legal and accounting fees are
              typically paid from operating income, we are estimating that two
              years of expense may be spent from Fund reserves until revenue
              reaches such levels.
iii)          Insurance expense represents $53,282 annually of Directors and
              Officers coverage that is allocated equally over 12 months in
              addition to well control insurance that is expensed in the quarter
              the well is spud (starts drilling). The well control insurance
              expense varies by well based on the projected depth of the well
              and as the Fund's working interest percentage in the well.
iv)           There will be additional well control insurance which cannot be
              estimated at the current time if one of the above wells is deemed
              unsuccessful.

Cash Reserves

The Fund is maintaining cash reserves of $4 million to be used for cost
overruns, new projects, project development costs or Fund expenses.

Item 3.  Quantitative and Qualitative Disclosures about Market Risk

The principal market risks to which the Fund is exposed that may adversely
impact the Fund's results of operations and financial position are changes in
oil and gas prices. The Fund has no market risk sensitive instruments held for
trading purposes.


Item 4.  Controls and Procedures

(a)     Evaluation of Disclosure Controls and Procedures

The Fund's Chief Executive Officer and Chief Financial Officer, with the
participation and assistance of other members of management, have evaluated the
effectiveness of the design and operation of the Fund's disclosure controls and
procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the
Securities Exchange Act of 1934, as amended) as of the end of the period covered
by Quarterly Report on Form 10-Q. Based upon that evaluation, the Fund's Chief
Executive Officer and the Chief Financial Officer have concluded that the Fund's
disclosure controls and procedures are effective, as of the end of the period
covered by this Quarterly Report on Form 10-Q.

We do not expect that our disclosure controls or our internal controls will
prevent all errors and all instances of fraud. A control system, no matter how
well conceived and operated, can provide only reasonable, not absolute,
assurance that the objectives of the system are met. Further, the design of a
control system must reflect the fact that there are resource constraints, and

                                       11
<PAGE>

the benefits of controls must be considered relative to their costs. Because of
the inherent limitations in all control systems, no evaluation of controls can
provide absolute assurance that we have detected all our control issues and
instances of fraud, if any. The design of any system of controls also is based
partly on certain assumptions about the likelihood of future events, and there
can be no assurance that any design will succeed in achieving its stated goals
under all potential future conditions.

(b)     Changes in Internal Control over Financial Reporting

No change in the Fund's internal control over financial reporting occurred
during the Fund's most recent fiscal quarter that has materially affected, or is
reasonably likely to materially affect, the Fund's internal control over
financial reporting.
