                          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.

The Manager performs (or arranges for the performance of) the management and
administrative services required for Fund operations. Such services include,
without limitation, the administration of shareholder accounts, shareholder
relations and the preparation, review and dissemination of tax and other
financial information. In addition, the Manager provides office space, equipment
and facilities and other services necessary for Fund operations. The Manager
also engages and manages the contractual relations with outside custodians,
depositories, accountants, attorneys, broker dealers, corporate fiduciaries,
insurers, banks and others as required (Notes 2 and 3).

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.



                                       7

     Oil and gas properties

Investments in oil and gas properties are 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.

In April 2005, the Financial Accounting Standards Board (FASB) issued FASB Staff
Position FAS 19-1, "Accounting for Suspended Well Costs." FAS 19-1 has been
applied to the Fund's financial statements to the earliest period presented.
Costs of acquisition of mineral interests and drilling exploratory wells are
capitalized pending determination of whether the well has found proved reserves.
Capitalized exploratory drilling costs are assessed on a quarterly basis for
impairment of value by evaluating and monitoring if sufficient progress is made
on assessing the reserves. Capitalized costs are expensed as dry hole costs in
the event of impairment or reserves are determined to be not proved. Dry hole
costs were $755,305 and $1,240,854 for the three and six months ended June 30,
2005, respectively.

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.

The volume of gas sold by the operator on the Fund's behalf may differ from the
volume of gas to which the Fund is entitled. The Fund accounts for such gas
production imbalances by the entitlements method. Under the entitlements method,
the Fund recognizes a receivable from other working interest owners for volumes
oversold by other working interest owners, and a payable to other working
interest owners for volumes oversold by the Fund. Through June 30, 2005, there
were no gas-balancing arrangements between the Fund and other working interest
owners.

Interest income is recognized when earned.

     Assets Retirement Obligations

For a substantial portion of the assets, there are obligations to perform
removal and remediation activities when the asset is retired. Through June 30,
2005, asset retirement obligations have been determined to be insignificant to
have a material effect on the operations of the Fund.

     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 value to the estimated
future undiscounted 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 of proved properties are depleted
(or amortized) on the basis of units of production and total estimated units of
proved developed reserves. For the three and six months ended June 30, 2005,
depletion and amortization totaled $829,390 and $1,216,731, respectively.



                                       8

     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 by the Fund out of operating revenue (not
including cash flow from distributions and investor capital contributions) from
producing wells, less operating expenses and other expenditures relating to the
producing wells and less reserves for operating expenses, plug and abandonment
costs and certain other actual and contingent liabilities. 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. As of June 30, 2005 $789,868 was due from the Manager.

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,
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.

 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.

5. Subsequent Event

Beginning on October 1, 2005 and for the remaining life of the Fund, the Manager
has elected to waive its management fee.

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


 The loss from operations for the three months ended June 30, 2005 and 2004 was
$1,759,661 and $2,769,290, respectively. Oil and gas revenues for East Cameron
299 for the three months ended June 30, 2005 totaled $640,972. Total production
for the quarter approximated 1,445,000 MCFs. Costs associated with the EC299
well include depreciation and amortization and lease operating expenses totaling
$981,032. Expenses related to unsuccessful properties including dry hole costs
and well control insurance totaled approximately $954,353 for the quarter.
Management fees of $442,875 and general and administrative costs of $22,373
comprised the remainder of the Fund's quarterly expenses. The loss for the
quarter ended June 30, 2004 was comprised primarily of the one-time investment
fee of $2,639,905 and the management fee of $76,375, both of which are payable
to the Manager. The other $53,010 of expenses consisted of accounting, legal and
general and administrative costs.

For the six months ended June 30, 2005 and 2004, the loss from operations was
$2,719,534 and $2,769,290, respectively. The loss attributable to the EC299 well
was approximately $370,406 for the six months ended June 30, 2005. Expenses
related to unsuccessful properties including dry hole costs and well control
insurance totaled approximately $1,419,902 for the period. Management fees and
other general and administrative expense through June 30, 2005 totaled $885,750
and $43,476, respectively. The loss for the period ended June 30, 2004 was
comprised primarily of the one-time investment fee of $2,639,905 and the
management fee of $76,375, both of which are payable to the Manager. The
remaining $53,010 of expenses consisted of accounting, legal and general and
administrative costs.

                                       10
<PAGE>

Beginning on October 1, 2005 and for the remaining life of the Fund, the
Manager has elected to waive its management fee to compensate for the large
capital losses incurred as dry hole costs which should improve the overall
results of the Fund.

Other Income

Other income, comprised solely of interest income, was $77,839 and $140,468 for
the three and six months ended June 30, 2005, respectively. Interest income for
the three months and period from March 1, 2004 (inceptions) through June 30,
2004 was $26,479. Interest is earned on non-invested capital which is held in
highly liquid investments with maturities when purchased of three months or
less.


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.
Net operating cash flows decreased approximately $1 million primarily due to the
expenditure of management fees and other operating expenses partially offset by
interest earned on non-invested cash.

During the period ended June 30, 2005, the Fund made expenditures for oil and
gas properties totaling $6.7 million. Of this total, $3.7 million represented
dry hole costs, $1.9 million was capitalized to proved properties and $1.1
million was capitalized to exploratory drilling costs.

Through June 30 2005, the Fund has made one distribution to its shareholders.
The total distributions made to shareholders (not including the Manager) through
June 2005 totaled $186,388. The Manager may distribute available cash from
operations which includes cash received by the Fund from producing wells (not
including cash flow from dispositions and investor capital contributions), less
operating expenses and other expenditures and less reserves for operating
expenses, plug and abandonment costs and certain other actual and contingent
liabilities.


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 $5.4 million, all of which is expected to be paid
within the following 12 months.



                                       11
<PAGE>


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 through September 30, 2005. 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 and we develop a different, unspecified project.
     v)   Effective October 1, 2005 the Manager waived its management fee for
          the remaining life of the fund.


Cash Reserves


The Fund is maintaining cash reserves of $4.6 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
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.
