IRONWOOD ISABELLE SMALL COMPANY STOCK FUND

SHAREHOLDER LETTER

To our Valued Shareholders:

No doubt you have heard the phrase "patience is a virtue" and just as likely
found an exception to that paradigm that has had a personal impact. The fact is
that many adages get to be so, because they are borne out the vast majority of
the time. With that in mind, I am pleased to report that your Fund's Investment
shares returned 23.68% for the year ended December 31, 2006, surpassing the
18.37% gain in the Russell 2000 Index by more than 5%.*

Refocusing the portfolio to have fewer holdings has been gradual and not without
some interim difficulties, but has allowed us to concentrate our efforts on
individual positions with increased intensity. We have said it before, and will
repeat it again, as it cannot be overstated, that the success of the Fund's
investments, we believe, is directly proportional to the level of understanding
we can bring to each of its holdings. We have always enjoyed the analytical
odyssey of searching for undervalued names, researching them as thoroughly as we
are capable, and developing from those efforts an investment thesis that offers
significant potential rewards to Fund shareholders over the longer term. The ART
is in what we make of a given situation - we want to find anomalies where we can
separate the actual risk from the commonly perceived risk. The SCIENCE is the
leg work required to understand how a given firm creates economic value and then
making a determination of how much of that value exists today and what can be
created over our investment horizon. With the right `hunch' and subsequent
conviction derived from our efforts, a solid portfolio of stocks, each offering
significant upward potential, but with individually different characteristics of
risk and reward, can be built.

Several years ago, for reasons that are unimportant now, we were pulled away
from that focus and the intensity of our efforts was diluted among far too many
portfolio holdings. Mind you, there are very good managers who have produced
better than average results with portfolios that are diversified across a very
large number of names, but that is not what we are good at. Thus, after some
painful introspection we realized that we needed to act in a manner that better
reflected our talents and skills, and began the refocusing process.

                                        1




That process is on-going but I would suggest that we reached a point of
equilibrium early last year, after paring the number of holdings to forty or so.
While the small cap markets continued to perform well, despite repeated
admonitions that the END WAS NEAR, we believe your portfolio provided the BANG
FOR THE BUCK that its sharpened focus should provide. Moreover, that BANG came
from a variety of sectors and industries, as you should expect from a
diversified portfolio. Finally, as we have suggested in the past, we have been
far less tolerant in allowing undue risk to develop within any of our holdings,
and we will not rely unduly on the hope that the value to be realized is so
compelling as to keep us there.

For all of these reasons, the portfolio has recently performed more to our
expectations, but it has required patience. Our investments are purchased for
long term appreciation, and there are periods where either market, or industry,
or company-specific forces will adversely impact performance -for a time. If,
however, we have done our homework sufficiently and correctly, as a very famous
investor once said, "The value will out."

The year progressed in just such a fashion. The first quarter was particularly
rewarding, as our investments in energy, basic materials, and health care all
performed very well. But, just as quickly the second quarter saw fears that
inventories were building across the industrial economy and energy and commodity
prices had run their course, causing many of our earlier out performers to
retreat to a significant degree. The second half of the year was somewhat more
subdued, but your portfolio benefited immensely as it became clear that the sky
was not falling on the basic materials sector, or the entire economy for that
matter, and that interest rates would remain stable and near historic lows,
which of course bodes well for security valuations. This scenario, we propose,
instilled a much greater level of confidence among investors and management,
which, aided by more than ample monetary liquidity, touched off a wave of merger
and acquisition activity across the entire spectrum of market capitalizations.

We were gratified and offer as testimonial to the validity of our investment
philosophy and process to see that a number of our holdings, as businesses, were
considered attractive enough to warrant acquisition either by competitors, or
private equity investment groups, several at very substantial premiums to both
the current price and historical cost. ALERIS (ARS), formerly Commonwealth
Aluminum, which we had held for several years, was acquired by Texas Pacific
Group in December of last

                                        2




year for $52.50 per share, producing a gain of more than 61% for the year, and
more than 900% over our average cost of $5.22 per share. BROADWING (BWNG), a
telecommunications company which we have in the past discussed at length, was
also effectively acquired last year by Level Three Communications and although
the formal closing was January 4, 2007, the final price, $15.65 per share,
represented a premium of about 159% over the 2005 year end closing price, and
284% above our average cost of $4.08. Further, SIRNA THERAPEUTICS (RNAI), a
small biotech company with very promising technology in the field of short
interference RNA, was bought by Merck for $13 per share. Again that merger was
formally consummated on January 3rd of 2007, but represented a gain of 154% over
average cost and 329% over the 2005 year end closing price. In fact your Fund
benefited from no less than seven acquisitions, which in addition to the three
aforementioned included WESTERN SILVER (WTZ) (+149% year; +290% cost), NAVIGANT
INTERNATIONAL (FLYR) (+52% year; +49% cost), RUSSELL CORP. (RML) (+34% year;
+35% cost), and DATASTREAM (DSTM) (+19% year; +50% cost). The combined impact of
this activity on portfolio performance was obviously significant, but equally as
important was the diversification in the source of those returns. Represented
were basic materials, telecommunications, healthcare, consumer service, consumer
non-durables, and technology.

Conversely, even as we made our share of missteps, we were again better at
mitigating risk by eliminating poor performers quickly. For example we sold
NEOPHARM (NASDAQ: NEOL), a small biotechnology company with a promising but
ultimately unapprovable therapy for treating gliomas, a deadly form of brain
cancer, when it became unclear to us that their phase III trial would produce
results satisfactory for eventual drug approval. We sold our shares between $5
and $6 per share against a cost of about $8.40. The loss, while significant,
pales in comparison to what would have been realized had we held on: NEOPHARM
closed the year at $1.67.

In all we added fourteen new positions last year, with two, CHEROKEE
INTERNATIONAL (NASDAQ: CHRK) and CHIQUITA BRANDS (NYSE: CQB), being names that
we had held in the past. We sold, including those names involved in acquisition
transactions, twenty-three positions.

Going into 2007 we are relatively comfortable with the composition of the
portfolio, although because of the heightened acquisition activity, the number
of holdings was reduced to just thirty-five by the end of the year. We are thus
actively seeking some new investment candidates, but

                                        3




we will, as always, do so judiciously and deliberately, maintaining focus on, as
well as sensitivity to, both valuation and risk.

Looking out, the economic environment seems to pose somewhat of a quandary. The
general economy appears to be chugging along as ever, but the markets, although
continuing their ascent, look to be somewhat extended. As such we must remain
diligent in assessing and reassessing our positions in light of what might be
rapidly changing circumstances. That said, we feel that your portfolio has a
great deal of yet unrealized potential that is poised to manifest itself over
the coming months. Some holdings are newer and will take time to mature, but we
feel that there are a number of companies that we have been patient with that
are positioned to perform well during this year.

We appreciate the patience and support of our shareholders, and we will continue
to work diligently at producing the kind of result that such patience warrants.

Respectfully submitted,

/s/ Warren J. Isabelle

IRONWOOD ISABELLE SMALL COMPANY STOCK FUND
NOTES TO FINANCIAL STATEMENTS

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

Ironwood Isabelle Small Company Stock Fund (formerly known as ICM/Isabelle Small
Cap Value Fund) (the "Fund") is a series of Ironwood Series Trust (formerly
known as ICM Series Trust) (the "Trust"), which was organized as a Massachusetts
business trust pursuant to a Declaration of Trust dated November 18, 1997. The
Trust is registered under the Investment Company Act of 1940, as amended (the
"1940 Act"). The Fund offers two classes of shares, Investment Shares and
Institutional Shares (collectively, the "Shares"), each of which has equal
rights as to class and voting privileges. The Investment Shares have exclusive
voting rights with respect to its distribution plan pursuant to Rule 12b-1 under
the 1940 Act ("12b-1 Plan") and are subject to 12b-1 Plan expenses. The Fund
commenced operations on March 9, 1998 (March 27, 1998 for the Institutional
Shares). The investment objective of the Fund is to seek capital appreciation by
investing its assets primarily in relatively undervalued common stocks of
domestic small companies. The following is a summary of significant accounting
policies consistently followed by the Fund in the preparation of its financial
statements. The policies are in conformity with accounting principles generally
accepted in the United States of America for investment companies.

      A. SECURITY VALUATION. Exchange traded securities and over-the-counter
      securities listed on the NASDAQ National Market System for which market
      quotations are readily available are valued using the last reported sales
      price or the NASDAQ Official Closing Price ("NOCP"), provided by
      independent pricing services as of the close of trading on the New York
      Stock Exchange (normally 4:00 p.m. Eastern time), on each Fund business
      day. In the absence of a sale or NOCP, such securities are valued at the
      mean of the last bid and asked price. Non-exchange traded securities for
      which quotations are available are generally valued at the mean between
      the current bid and asked prices. Money market instruments that mature in
      sixty days or less may be valued at amortized cost.

                                       18




IRONWOOD ISABELLE SMALL COMPANY STOCK FUND
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2006 - (Continued)

      The Fund values securities at fair value pursuant to procedures adopted by
      the Trust's Board of Trustees (the "Board") if (1) market quotations are
      insufficient or not readily available; or (2) the Adviser believes that
      the prices or values available are unreliable. Fair valuation is based on
      subjective factors and as a result, the fair value price of an asset may
      differ from the asset's market price and may not be the price at which the
      asset may be sold. Fair valuation could result in a different net asset
      value ("NAV") than a NAV determined by using market quotes.

      B. INVESTMENT INCOME AND SECURITIES TRANSACTIONS. Securities transactions
      are accounted for on the date the securities are purchased or sold (trade
      date). Cost is determined and gains and losses are based on the identified
      cost basis for both financial statement and federal income tax purposes.
      Dividend income is accrued and reported on the ex-dividend date. Interest
      income and expenses are accrued daily.

      C. NET ASSET VALUE PER SHARE. Net Asset value per share of each class of
      shares of the Fund is determined daily as of the close of trading on the
      New York Stock Exchange by dividing the value of the total assets, less
      liabilities attributable to that class, by the number of outstanding
      shares of that class. The net asset value of the classes may differ
      because of different fees and expenses charged to each class.

      D. FEDERAL INCOME TAXES. The Fund intends to continue to qualify each year
      as a regulated investment company by complying with all requirements of
      the Internal Revenue Code of 1986, as amended, applicable to regulated
      investment companies including, among other things, distributing
      substantially all of its earnings to its shareholders. Therefore, no
      federal income tax provision is required. The characterization of
      distributions to shareholders for financial reporting purposes is
      determined in accordance with federal income tax rules.

      For the fiscal year ended December 31, 2006, the Fund reclassified
      $909,268 to increase net investment income (loss), $398,091 to increase
      accumulated net realized loss on investments and $511,177

                                       19

NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2006 - (Continued)

      to decrease paid-in-capital. The reclassification has no impact on the net
      asset value of the Fund and is primarily due to net operating losses.

      As of December 31, 2006, distributable earnings on a tax basis were as
      follows:

            Unrealized Appreciation (Depreciation) $ 13,418,398

      The tax character of distributions paid during 2006 and 2005 were as
      follows:

                                          2006            2005
                                      -----------     -----------
            Ordinary Income           $   396,930     $     4,097
            Long-Term Capital Gain     11,741,585      10,537,375
                                      -----------     -----------
            Total                     $12,138,515     $10,541,472
                                      ===========     ===========

      E. INCOME AND EXPENSES. Expenses directly attributable to a particular
      class are charged directly to such class. In calculating net asset value
      per share of each class, investment income, realized and unrealized gains
      and losses and expenses, other than class specific expenses, are allocated
      daily to each class of shares based on the proportion of net assets of
      each class at the beginning of that day.

      F. REPURCHASE AGREEMENTS. The Fund may invest in repurchase agreements.
      The Fund will require the financial institution with which the Fund enters
      into a repurchase agreement to maintain collateral at all times with a
      value equal to the amount the Fund paid for the securities. In the event
      of default, the Fund may have difficulties with the disposition of any
      securities held as collateral.

      G. DISTRIBUTIONS TO SHAREHOLDERS. The Fund will distribute substantially
      all of its net investment income and capital gains, if any, at least
      annually. Distributions to shareholders are recorded on the ex-dividend
      date. Income and capital gain distributions are determined in accordance
      with income tax regulations, which may differ from accounting principles
      generally accepted in the United States of America.

      H. NEW ACCOUNTING PRONOUNCEMENTS. In June 2006, Financial Accounting
      Standards Board issued Financial Interpretation No. 48, Accounting for
      Uncertainty in Income Taxes (the "Interpretation") which is effective for
      fiscal years beginning after December 15, 2006 and is to be applied to all
      open tax years no later than June 30, 2007. This Interpretation prescribes
      a minimum threshold for financial statement recognition of the benefit of
      a tax position taken or expected to be taken in a tax return, and requires
      certain expanded disclosures. Management has recently begun to evaluate
      the application of the Interpretation to the Fund, and has not at this
      time determined the impact, if any, resulting from the adoption of this
      Interpretation on the Fund's financial statements.

      In September 2006, the FASB issued Statement of Financial Accounting
      Standards No. 157 "Fair Value Measurements" ("SFAS 157") which is
      effective for fiscal years beginning after November 15, 2007, and interim
      periods within those fiscal years. SFAS 157 defines fair value,
      establishes a framework for measuring fair value in generally accepted
      accounting principles, and expands disclosures about fair value
      measurements. Management has recently begun to evaluate the application of
      SFAS 157, and has not at this time determined the impact, if any,
      resulting from its adoption on the Fund's financial statements.

      In September 2006, the SEC issued Staff Accounting Bulletin 108,
      CONSIDERING THE EFFECTS OF PRIOR YEAR MISSTATEMENTS WHEN QUANTIFYING
      MISSTATEMENTS IN CURRENT YEAR FINANCIAL STATEMENTS ("SAB 108"). SAB 108
      provides interpretive guidance on how the effects of the carryover or
      reversal of prior year financial statement misstatements should be
      considered in quantifying a current year misstatement. SAB 108 is
      effective for financial statements covering the first fiscal year ending
      after November 15, 2006. There was no material impact of the Fund's
      adoption of SAB 108 on it financial condition or results of operation.

      I. USE OF ESTIMATES. In preparing financial statements in conformity with
      accounting principles generally accepted in the United States of America,
      management makes estimates and assumptions that affect the reported
      amounts of assets and liabilities at the date of the financial statements,
      as well as the reported amounts of revenues and expenses during the
      reporting period. Actual results could differ from those estimates.

NOTE 2 - PURCHASES AND SALES OF SECURITIES

Purchases and sales of securities, other than short-term investments, aggregated
$84,511,790 and $99,780,338, respectively, for the fiscal year ended December
31, 2006.

NOTE 3 - ADVISORY FEES, SERVICING FEES, AND OTHER TRANSACTIONS WITH
         RELATED PARTIES

INVESTMENT ADVISER - Ironwood Investment Management, LLC (formerly known as
Ironwood Capital Management, LLC) ("Ironwood") serves as the investment adviser
for the Fund pursuant to an investment advisory agreement (the "Agreement").
Under the terms of the Agreement, Ironwood receives an investment advisory fee
from the Fund, accrued daily and paid monthly, at an annual rate of 1.00% of the
average daily net assets of the Fund. Pursuant to the terms of the Agreement,

Agreement," and, collectively with the Interim Agreement and the Agreement, the

also approved by the Board on October 17, 2005. The terms, including without
limitation the advisory fee, of each of the Advisory Agreements, are the same in
all material respects, except with respect to those terms related to duration of
each Advisory Agreement, and execution and termination dates. The basis of the

the Fund's Annual Report dated December 31, 2005.

for its distribution services.

Under a Compliance Services Agreement with the Fund, the Distributor provided a
Chief Compliance Officer to the Fund as well as certain additional compliance
support functions ("Compliance Services") during the fiscal year ended December
31, 2006. Since February 22, 2007, the Compliance Services have been provided by
Foreside Compliance Services, LLC ("FCS"), an affiliate of the Distributor,
pursuant to a Compliance Services Agreement between Citigroup and the Fund.
Neither the Distributor nor Citigroup has any role in determining the investment

the Fund, based on its borrowings, at a rate equal to the rate of interest on
overnight facilities which the Custodian is offering to other borrowers and
potential borrowers of comparable financial condition on the business day that a
loan is made pursuant to the agreement.

During the fiscal year ended December 31, 2006, the Fund was charged $19,522
from borrowings under the line of credit. As of December 31, 2006, the Fund had

NOTE 5 - DISTRIBUTION PLAN

The Trustees of the Fund have adopted a 12b-1 Plan with respect to the
Investment Shares pursuant to Section 12(b) of the 1940 Act and Rule 12b-1
thereunder, which permits the Fund to pay certain expenses associated with the
distribution of its Investment Shares. Under the 12b-1 Plan, the Fund
compensates the Distributor, at a fee calculated at an annual rate of up to
0.25% of the value of the average annual net assets attributable to the
Investment Shares for distribution expenses borne, or paid to others, by the
Distributor. For the fiscal year ended December 31, 2006, the Fund incurred
$157,543 in distribution costs for Investment Shares.

NOTE 6 - PAYMENTS BY AFFILIATE & OTHER SERVICE PROVIDER

For the year ended December 31, 2005, Citigroup reimbursed the Fund to offset an
accounting error. As a result, the Fund reimbursed the shareholders who placed
trades during the re-evaluation period. In order to compensate the Fund for the
overstated number of shares issued to subscribing shareholders during the
re-evaluation period, Citigroup reimbursed the Fund for the dollar value of
these shares. This amount is reflected as payment by other service provider on
the Statements of Changes in Net Assets. This payment had no effect on the total
return of the Fund.

NOTE 7 - OTHER INFORMATION

On December 31, 2006, 2 shareholders held approximately 48% of the outstanding
shares of the Fund. These shareholders are omnibus accounts, which are held on
behalf of several individual shareholders.

IRONWOOD ISABELLE SMALL COMPANY STOCK FUND
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Trustees
of the Ironwood Series Trust:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the Ironwood Isabelle Small Company Stock Fund,
a series of the Ironwood Series Trust (the "Fund"), as of December 31, 2006, and
the related statements of operations, and changes in net assets for each of the
two years in the period then ended and the financial highlights for each of the
two years in the period then ended. The financial highlights for the three years
ended December 31, 2004 were audited by another independent registered public
accounting firm whose report dated February 17, 2005 expressed an unqualified
opinion on those statements. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audit.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. The Fund
is not required to have, nor were we engaged to perform an audit of the Fund's
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Fund's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements and financial highlights, assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. Our procedures
included confirmation

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

of securities owned as of December 31, 2006, by correspondence with the
custodian and brokers. We believe that our audits provide a reasonable basis for
our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
Ironwood Isabelle Small Company Stock Fund as of December 31, 2006, the results
of its operations, changes in net assets and financial highlights for each of
the two years in the period then ended, in conformity with accounting principles
generally accepted in the United States of America.

SHAREHOLDER EXPENSES

As a shareholder of the Fund, you incur ongoing costs, including management
fees, distribution fees with respect to Investment Shares and other Fund
expenses. This example is intended to help you understand these ongoing costs
(in dollars) of investing in the Fund and to compare these costs with the
ongoing costs of investing in other mutual funds.

The following example is based on $1,000 invested at the beginning of the period
and held for the entire period from July 1, 2006 through December 31, 2006.

ACTUAL EXPENSES - The first line of the table below provides information about
actual account values and actual expenses. You may use the information in this
line, together with the amount you invested, to estimate the expenses that you
paid over the period. Simply divide your account value by $1,000 (for example,
an $8,600 account value divided by $1,000

= 8.6), then multiply the result by the number in the first line under the
heading "Expenses Paid During Period" to estimate the expenses you paid on your
account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES - The second line of the table
provides information about hypothetical account values and hypothetical expenses
based on the Fund's actual expense ratio and an assumed rate of return of 5% per
year before expenses, which is not the Fund's actual return. The hypothetical
account values and expenses may not be used to estimate the actual ending
account balance or expenses you paid for the period. You may use this
information to compare the ongoing cost of investing in the Fund and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of other funds.

Please note that expenses shown in the table are meant to highlight your ongoing
costs only and do not reflect any transactional costs. Therefore, the second
line of the table is useful in comparing ongoing costs only, and will not help
you determine the relative total costs of owning different funds. In addition,
if these transactional costs had been included, your costs would have been
higher.

          the Registrant's principal accountant for the audit of the
          Registrant's annual financial statements, or services that are
          normally provided by the principal accountant in connection with the
          statutory and regulatory filings or engagements for the Reporting
          Periods, were $20,000 in 2005 and $25,125 in 2006.

     (b)  Audit-Related Fees - The aggregate fees billed in the Reporting
          Periods for assurance and related services rendered by the principal
          accountant that were reasonably related to the performance of the
          audit of the Registrant's financial statements and are not reported
          under paragraph (a) of this Item 4 were $0 in 2005 and $0 in 2006.

     (c)  Tax Fees - The aggregate fees billed in the Reporting Periods for
          professional services rendered by the principal accountant to the
          Registrant for tax compliance, tax advice and tax planning ("Tax
          Services") were $2,500 in 2005 and $2,800 in 2006. These services
          consisted of review or preparation of U.S. federal, state, local and
          excise tax returns.

     (d)  Other Fees - There were no other fees billed in the Reporting Periods
          for products and services provided to the Registrant by the principal
          accountant, other than the services reported above.

     (e)  (1) Pursuant to the Registrant's Audit Committee Charter (the
          "Charter"), before an auditor is engaged by the Registrant to render
          audit services, the Audit Committee must review and approve the
          engagement. In addition, the Registrant's Audit Committee must review
          and approve in advance any proposal that the Registrant employ its
          auditor to render "permissible non-audit services" (as defined in the
          Charter consistent with Rule 2-01(c)(4) of Regulation S-X), except as
          described below. The Committee must also review and approve in advance
          any proposal (except as set forth below) that the investment adviser,
          and any entity controlling, controlled by, or under common control
          with the adviser that provides ongoing services to the Registrant (an
          "Adviser-affiliated service provider"), employ the Registrant's
          auditor to render non-audit services, if the engagement would relate
          directly to the operations and financial reporting of the Registrant.
          As a part of its review, the Committee must consider whether the
          provision of such services is consistent with the auditor's
          independence. Pre-approval by the Committee of non-audit services is
          not required if: (1) (A) with respect to the Registrant, the aggregate
          amount of all such permissible non-audit services provided to the
          Registrant constitutes no more than 5% of the total amount of revenues
          paid to the auditor by the Registrant during the fiscal year in which
          the services are provided or (B) with respect to the adviser and any
          Adviser-affiliated service provider, the aggregate amount of all such
          non-audit services provided constitutes no more than 5% of the total
          amount of revenues (of the type that would have to be pre-approved by
          the Committee) paid to the auditor by the Registrant, the Adviser and
          any Adviser-affiliated service provider during the fiscal year in
          which the services are provided; (2) such services were not recognized
          by the Registrant at the time of the engagement to be non-audit
          services; and (3) such services are promptly brought to the attention
          of the Committee and approved prior to the completion of the audit by
          the Committee or its Delegate(s) (as defined below). The Committee may
          delegate to one or more of its members ("Delegates") authority to
          pre-approve the auditor's provision of audit services or permissible
          non-audit services to the Registrant, or the provision of




          non-audit services to the Adviser or any Adviser-affiliated service
          provider. Any pre-approval determination made by a Delegate shall be
          presented to the full Committee at its next meeting. The Committee
          shall communicate any pre-approval made by it or a Delegate to
          Registrant's fund administrator, who will ensure that the appropriate
          disclosure is made in the Registrant's periodic reports and other
          documents as required under the federal securities laws.

     (e)  (2) No services included in (b) - (d) above were approved pursuant to
          paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

     (f)  Not applicable as less than 50%.

     (g)  The aggregate non-audit fees billed by the principal accountant for
          services rendered to the Registrant for the Reporting Periods were
          $2,500 in 2005 and $2,800 in 2006. There were no fees billed in each
          of the Reporting Periods for non-audit services rendered by the
          principal accountant to the investment adviser.

     (h)  The Registrant's Audit Committee has considered whether the provision
          of any non-audit services rendered to the investment adviser, to the
          extent applicable, that were not pre-approved (not requiring
          pre-approval) is compatible with maintaining the Auditor's
          independence. Any services provided by the principal accountant to the
          Registrant or to the investment adviser requiring pre-approval were
          pre-approved as required.

          occurred during the registrant's last fiscal quarter that have
