             Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors
Tridan Corp.

We have audited the accompanying  statements of assets and liabilities of Tridan
Corp.  (the  "Company"),  including  the schedules of  investments  in municipal
obligations,  as of April  30,2008  and  2007,  and the  related  statements  of
operations for the years then ended,  and the statement of changes in net assets
and the  financial  highlights  for the  each of the  three  years  ended  April
30,2008.   These   financial   statements  and  financial   highlights  are  the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these  financial  statements  and financial  highlights  based on our
audits.

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.  An audit
includes  examining,  on a test  basis,  evidence  supporting  the  amounts  and
disclosures in the financial statements. Our procedures included confirmation of
securities  owned,  as of April 30, 2008 and 2007,  by  correspondence  with the
custodian.  An audit also includes assessing the accounting  principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   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 Tridan
Corp. as of April 30,2008 and 2007,  the results of its operations for the years
then ended,  and the changes in its net assets and its financial  highlights for
each of the three years ended  April  30,2008,  in  conformity  with  accounting
principles generally accepted in the United States of America.

1.    Significant accounting policies

      The following is a summary of the significant accounting policies followed
      by Tridan Corp. (the "Company"), a closed-end,  non-diversified management
      investment  company,  registered under the Investment Company Act of 1940,
      in the preparation of its financial statements.

      Acquisition and valuation of investments

      Investment  transactions  are accounted for on the date the securities are
      purchased/sold  (trade date) and interest on securities  acquired/sold  is
      included in income from/to the settlement date. Short-term investments are
      stated at cost, which is equivalent to fair value.

      Fair values for the Company's  investments in municipal  obligations  have
      been determined  based on the bid price of the obligation.  Securities for
      which  quotations  are not readily  available  are valued at fair value as
      determined by the board of directors.  There were no securities  valued by
      the board of directors,  for which quotations were not readily  available,
      as of April 30, 2008 and 2007.

      Amortization of bond premium or discount

      In determining investment income, bond premiums or discounts are amortized
      over the remaining term of the obligation.

      Income taxes

      It is the Company's policy to comply with the requirements of the Internal
      Revenue Code that are applicable to regulated  investment companies and to
      distribute  substantially  all of its taxable income to its  shareholders.
      Therefore, no income tax provision is required.

      Interest  income from  municipal  investments  are exempt from Federal and
      state income taxes.

      Cash and cash equivalents

      The Company  considers all investments that can be liquidated on demand to
      be cash equivalents.

      Use of estimates

      The  preparation  of financial  statements,  in conformity  with generally
      accepted accounting principles,  requires management to make estimates and
      assumptions that affect the reported amounts of assets and liabilities and
      disclosures  of  contingent  assets  and  liabilities  at the  date of the
      financial  statements and the reported  amounts of increases and decreases
      in net assets from operations during the reporting period.  Actual results
      could  differ  from those  estimates.  Significant  estimates  are used in
      determining the fair value of investments.

      Concentration of credit risk

      The Company's financial  instruments that are exposed to concentrations of
      credit  risk  consist   primarily  of  cash  and  cash   equivalents   and
      investments.  The  Company  maintains  all of its cash on  deposit  in one
      financial   institution.   The  cash   balance  at  April  30,   2008  was
      approximately  $1,180,000.  The value of the Company's  investments may be
      subject to possible  risks  involving,  among other things,  the continued
      credit  worthiness of the various state and local government  agencies and
      public financing authorities  underlying its investments.  The Company and
      its  investment  advisor  periodically  consider the credit quality of the
      Company's investments, and the Company adheres to its investment objective
      of investing only in investment grade securities.

      depreciation of approximately $93,000 and $108,000, respectively).

5.    Common stock, share redemption plan and net asset values

      At April 30, 2008 and 2007, there were 6,000,000 shares of $0.02 par value
      common stock  authorized of which  3,199,100  had been issued  aggregating
      $63,982, and initial additional paid-in capital aggregating $312,787.

      The Company has a share redemption plan applicable to approximately 43,000
      shares and 47,800 shares,  respectively,  of outstanding  common stock, at
      April 30, 2008 and 2007. The plan permits  eligible  shareholders or their
      estates to have their shares  redeemed upon reaching age 65 or upon death.
      Shares are redeemed at the net asset value per share, based on fair value,
      as of the end of the  Company's  fiscal  quarter in which the  request for
      redemption   is  received.   At  April  30,  2008  and  2007,   $1,072,256
      (91,234.6046 shares) and $1,016,426  (86,564.9839  shares),  respectively,
      had been redeemed under this plan and are held in treasury.

      The net asset value per share is calculated by dividing the aggregate fair
      value of all assets less the aggregate  fair value of all  liabilities  by
      the number of common shares outstanding at the end of the period.

      The net asset value per share and the shares outstanding were as follows:

                                                                   April 30,

                         POTENTIAL CONFLICTS OF INTEREST

As an investment advisor, J.P. Morgan Investment Management Inc. has a fiduciary
obligation to act in the best interests of its clients, and to avoid any
conflicts of interest. As such, JPMorgan Asset Management has adopted a
"Safeguard Policy" designed to prevent its investment management process from
being influenced by clients of other parts of the firm, as well as by clients of
the investment management business. Communications between personnel outside the
investment management business and investment professionals within J.P. Morgan
Investment Management Inc. are strictly limited.

JPMIM has adopted policies and procedures that are designed to ensure that
transactions undertaken with affiliates are allowable under current law and
client guidelines and that any potential conflicts of interest are recognized
and appropriately addressed.



JPMIM also has policies and procedures to monitor personal trading activities of
its employees and certain members of their immediate families and any person to
whose support the employee significantly contributes. The policies and
procedures are generally intended to comply with JPMIM's Code of Ethics.

                         PORTFOLIO MANAGER COMPENSATION

The Adviser's portfolio managers participate in a competitive compensation
program that is designed to attract and retain outstanding people and closely
link the performance of investment professionals to client investment
objectives. The total compensation program includes a base salary fixed from
year to year and a variable performance bonus consisting of cash incentives,
restricted stock and, in most cases, mandatory deferred compensation. These
elements reflect individual performance and the performance of the Adviser's
business as a whole.

Each portfolio manager's performance is formally evaluated annually based on a
variety of factors including the aggregate size and blended performance of the
portfolios such portfolio manager manages. Individual contribution relative to
client goals carries the highest impact. Portfolio manager compensation is
primarily driven by meeting or exceeding clients' risk and return objectives,
relative performance to competitors or competitive indices and compliance with
firm policies and regulatory requirements. Investment performance is generally
more heavily weighted to the long term.

Awards of restricted stock are granted as part of an employee's annual
performance bonus and comprise from 0% to 35% of a portfolio manager's total
bonus. As the level of incentive compensation increases, the percentage of
compensation awarded in restricted stock also increases. Up to 50% of this
restricted stock portion of a portfolio manager's bonus may be subject to a
mandatory notional investment in selected mutual funds advised by the Adviser or
its affiliates.

               financial reporting that occurred during the second fiscal
               quarter of the period covered by this report that has materially
               affected, or is reasonably likely to materially affect, the
