5. Note Payable and Long-Term Debt (continued)

The credit facility with Huntington National Bank includes a mortgage on its
real estate for $2,000,000. The mortgage is a five year note, amortized over ten
years with monthly payments of $16,667.67 and a final balloon payment of
$1,000,000 due at maturity. Interest on the mortgage is at 1.75% (effective rate
of 7.5% at March 31, 2005) over the banks prime lending rate. Additionally, the
credit facility includes a $6,000,000 line of credit secured by all of the
Company's assets. The credit line is a three-year facility with an interest rate
of 1.25% (effective rate of 7.0% at March 31, 2005) over the bank's prime
lending rate and is payable monthly. The Company, at March 31, 2005, had
utilized $4,054,625 of its credit line with Huntington National Bank. The
Company is in violation of certain provisions in its credit agreement with
Huntington, including covenants relating to tangible net worth, a debt leverage
ratio, and a minimum fixed charge ratio. The Company is not seeking waivers from
Huntington for non-compliance with these provisions.

The Company's failure to obtain waivers for non-compliance with the credit
agreement could result in a default and the lender could elect to declare all
amounts outstanding to be immediately due and payable and terminate all
commitments to extend further credit. If we are unable to repay those amounts,
the lender could proceed against all collateral that secures the indebtedness.
If the lender under our current or future indebtedness accelerates the payment
of the indebtedness, we cannot assure that our assets or cash flow would be
sufficient to repay in full our outstanding indebtedness. As a result of these
circumstances, the Company reflected all of its existing lender debt as current,
though the lender has not accelerated term debt maturity or demanded payment.

6. Earnings (Loss) Per Share

For the three months ended March 31, 2005, and the three months ended March 31,
2004 all options outstanding have been excluded from the computation of diluted
earnings (loss) per share as the effect would be anti-dilutive.

9. Preferred Stock

   During June 2001, the Company issued 19,000 shares of 8.25% cumulative
   preferred stock (Series A) with a par value of $1 to the Trans-Industries,
   Inc. Employees 401(k) and Profit Sharing Plan for $1,900,000. Dividends in

9. Preferred Stock (continued)

   common stock for $1,500,000 to the Harry E. Figgie, Jr. Trust (the "Trust"),
   a trust controlled by a member of the Company's Board of Directors. Issuance
   costs were $217,000. The warrants have an exercise price of $3 per share. The
   warrants have been allocated a value of $195,000, which is the estimated fair
   value of the warrants on the date of the sale as determined by the
   Black-Scholes pricing model. The proceeds allocated to the Series B Stock are
   $1,305,000. The Series B Stock contains a beneficial conversion feature of
   $78,721 attributable to the difference between the ascribed value of the
   preferred stock and the market value of the underlying number of common
   shares into which the Series B Stock may be converted. The value assigned to
   the beneficial conversion feature is amortized from the date of issuance to
   the earliest conversion date and is treated as a dividend. Because the Series
   B Stock is convertible at any time after issuance, the entire beneficial
   conversion feature was charged directly to retained earnings. Following is a
   summary of the Series B Stock features.

   Dividends

   The holder of Series B Stock is entitled to receive cumulative quarterly
   dividends at a rate per annum of $0.387 per share, commencing on April 1,
   2004. The Company at its option, in no more than eight of the first twelve
   full quarters, may elect to pay the accruing dividends in additional shares
   of Series B Stock at $7.74 per share or in cash.

   Conversion

   At the holder's option, each share of Series B Stock is convertible into
   three shares of the Company's common stock. At any time after February 27,
   2007 and on the business day immediately following the period of 30
   consecutive business days on which trades occur during which the market price
   of the Company's common stock equals or exceeds $5.16 per share, each share
   of Series B Stock will automatically be converted into three shares of common
   stock

   Redemption

   At any time after February 27, 2007, the Company may, at its option, redeem
   all, but not less than all of the holder's unconverted shares of Series B
   Stock by paying cash equal to the stated value, $7.74 per share, plus all
   declared or accumulated but unpaid dividends.

   Liquidation

   In the event of any liquidation, dissolution or winding up of the Company,
   either voluntary or involuntary, the holder of each share of Series B Stock
   is entitled to receive, prior to and in preference to any distributions to
   the holders of common stock, an amount equal to the stated value of $7.74 per
   share, plus unpaid, accrued and accumulated dividends.

9. Preferred Stock (continued)

Voting rights

The holder of Series B Stock has the right to vote with other stockholders of
the Company on an as-converted basis.

Issuance of Subordinated Convertible Note

In connection with the initial closing of the sale of Series B Stock and related
warrants described above, the Company granted an option to the Harry E. Figgie,
Jr. Trust to purchase between 55,556 and 166,667 shares of Series B-1
Convertible Preferred Stock ("Series B-1 Stock") and related warrants for $9 per
share, including warrants. The option required approval by the Company's
stockholders pursuant to certain National Association of Securities Dealers,
Inc. ("NASD") rules providing for qualitative listing requirements applicable to
securities traded on the NASDAQ National Market and NASDAQ SmallCap Market. The
Company received stockholder approval at the Company's January 19, 2005 annual
meeting.

Huntington National Bank required an additional capital infusion as a condition
to the closing of the refinancing completed in August 2004. While the Harry E.
Figgie, Jr. Trust indicated willingness to provide the new capital, exercise of
the option discussed above was not possible until approval by the Company's
stockholders pursuant to NASD rules. Therefore, the Trust loaned the Company
$1,500,000 in exchange for a subordinated convertible note. Interest on the
subordinated note was at Huntington National Bank's prime lending rate plus
1.75% (effective rate of 7.00% at December 31, 2004). The principal and accrued
interest due under the note was convertible into a number of shares of Series
B-1 Stock calculated at a price of $9 per share and a number of warrants to
purchase shares of B-1 Stock equal to 25% of the number of shares of common
stock that the shares of Series B-1 Stock are convertible into. The holder of
shares of Series B-1 Stock is entitled to receive quarterly dividends at a rate
per annum of $0.45 per share. In addition, the shares of Series B-1 Stock have
conversion, redemption, and voting rights identical to those of the shares of
Series B Stock.

On January 19, 2005, the convertible promissory note holder converted the note
and received 166,667 shares of Series B-1 Stock and warrants to purchase 125,000
shares of common stock. The warrants have an exercise price of $3.00 per share.
The warrants have been allocated a value of $227,000, which is the estimated
fair value of the warrants on the date of the sale as determined by the
Black-Scholes pricing model. The preferred stock contains a beneficial
conversion feature of $217,000 attributable to the difference between the
ascribed value of the preferred stock and the market value of the underlying
number of common shares into which the preferred stock may be converted. The
value assigned to the beneficial conversion feature is amortized from the date
of issuance to the earliest conversion date and is treated as a dividend.
Because the preferred stock is convertible at any time after issuance, the
entire beneficial conversion feature was charged directly to retained earnings.
Following is a summary of the Series B-1 Stock features.

Preferred Stock (continued)

Dividends

The holder is entitled to receive cumulative quarterly dividends at a rate per
annum of $0.45 per share, commencing on April 1, 2005. The Company, at its
option and in no more than eight of the first twelve full quarters, may elect to
pay these dividends in the form of additional shares of Series B-1 Stock at a
stated amount of $9.00 per share, or in cash.

Conversion

At the holder's option, each share of Series B-1 Stock is convertible into three
shares of the Company's common stock. At any time after February 27, 2007 and on
the business day immediately following the period of 30 consecutive business
days on which trades occur during which the market price of the Company's common
stock equals or exceeds $5.16 per share, each share of Series B-1 Stock will
automatically be converted into three shares of common stock.

Redemption

At any time after February 27, 2007, the Company may, at its option, redeem all
outstanding shares of Series B-1 Stock by paying cash equal to the stated value
of $9.00 per share, plus all declared and accumulated but unpaid dividends.

Liquidation

In the event of any liquidation, dissolution or winding up of the Company,
either voluntary or involuntary, the holder of each share of Series B-1 Stock is
entitled to receive, prior to and in preference to any distributions to the
holders of common stock, an amount equal to the stated value of $9.00 per share,
plus declared and accumulated but unpaid dividends.

Voting rights

The holder of Series B-1 Stock has the right to vote with other stockholders of
the Company on an as-converted basis.

10. Stock Based Compensation

At March 31, the Company has a stock-based employee compensation plan, which is
described more fully in Notes B & I in the Company's Annual Report Form 10-K.
The Company accounts for this plan under the recognition and measurement
principles of APB Opinion No. 25, Accounting for Stock Issued to Employees, and
related Interpretations. No stock-based employee compensation cost is reflected
in net income, as all options granted under those plans had an exercise price
greater than or equal to the market value of the underlying common stock on the
date of grant. The following table illustrates the effect on

In December 2004, the FASB issued a revision of FAS 123, "Share-Based Payment"
(FAS 123R). FAS 123R requires that the compensation cost relating to share-based
payment transactions be recognized in financial statements. The cost to be
recognized will be measured based on the fair value of the equity or liability
instruments issued. The scope of FAS 123R includes a wide range of share-based
compensation arrangements including share options, restricted share plans,
performance-based awards, share appreciation rights and employee share purchase
plans. FAS 123R replaces FAS 123, "Accounting for Stock-Based Compensation," and
supersedes APB Opinion No. 25 (APB 25), "Accounting for Stock Issued to
Employees." As originally issued in 1995, FAS 123 established as preferable a
fair-value-based method of accounting for share-based payment transactions with
employees. However, that statement permitted entities the option of continuing
to apply the guidance of APB 25 as long as the footnotes to the financial
statements disclosed what net income would have been had the preferable
fair-value-based method been used. At that time, we determined to continue to
apply the guidance of APB 25 and make the required disclosures in our financial
statement footnotes. Accordingly, we will be required to change our method of
accounting for stock compensation costs. We will be required to adopt FAS 123R
as of January 1, 2006. FAS 123R applies only to those awards granted or which
become vested after the required effective date. We expect that the adoption of
FAS 123R in the first quarter of 2006 will have no material effect on our
results of operations, financial condition or cash flows.

Forward-Looking Statements

This discussion highlights significant factors influencing the financial
condition and results of operations of Trans-Industries, Inc. It should be read
in conjunction with the financial statements and related notes. This discussion
includes certain forward-looking statements based on management's estimate of
trends and economic factors in the markets in which the Company is active, as
well as the Company's business plans. We have used words such as "may", "will",
"expect", "anticipate", "believe", "estimate", "plan", "intend", and similar
expressions in this report to identify forward-looking statements. In light of
recent securities law developments, including the "safe harbor" provisions of
the Private Securities Litigation Reform Act of 1995, the Company notes that
such forward-looking statements are subject to risks and uncertainties.
Accordingly, the Company's actual results may differ from these set forth in
such statements. Among these are significant changes in economic conditions and
regulatory or legislative changes that can affect the Company, its competitors,
or the markets in which it is active. The Company believes any forward-looking
statements it has made are based on current management expectations and they are
subject to risks and uncertainties. These risks and uncertainties include, but
are not limited to the following:

      -     Uncertainties discussed in "Management's Discussion and Analysis"
            and those set forth elsewhere in this report and the Company's other
            SEC filings;

      -     The continued forbearance by the Company's bank lender of its right
            to call the Company's outstanding bank debt;

      -     A further decline of economic conditions in general and in the mass
            transit industry in particular;

      -     Changes in customer requirements or reduced demand for the Company's
            products and services;

      -     The inability of the Company to successfully implement its
            informational systems operation restructuring program;

      -     Competitive factors (including the introduction or enhancement of
            competitive products and their successful introduction into the
            marketplace);

      -     Product pricing decreases and component price increases that may
            result in materially reduced gross profit margins for the Company's
            products;

      -     Unforeseen increases in operating expenses; and

      -     The inability to attract or retain management, sales or engineering
            talent.

All of our forward-looking statements should be considered in light of the above
factors and all other risks discussed from time to time in our filings with the
Securities and Exchange Commission. We do not undertake to update our
forward-looking statements to reflect future events or circumstances.

Item 2.           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS

                    For The Three Months Ended March 31, 2005

Results of Operations

Sales for the first quarter of 2005 were $5,269,183 compared with $7,534,929 for
the same period a year ago. This decrease of $2,265,746 was primarily due to
decreased sales of the Company's lighting products and its digital display
products. Sales for lighting products and digital display products were down for
the first quarter of 2005 by approximately $1,735,000 and $895,000 respectively,
compared to the first quarter of 2004. Sales of dust abatement equipment
recorded a moderate increase of $348,000 for the first quarter of 2005 compared
to the same quarter of 2004. The reduction in lighting products revenues is a
result of reduced transit bus production, lower demand for the Company's modular
parcel racks, and market acceptance of a competitor's product. Reduced sales of
digital display products were primarily attributable to reduced sales of
overhead highway signs. Cost of sales for the first quarter of 2005 was
$4,175,441 compared with $5,605,874 for the first quarter of 2004. This
reduction of $1,430,433 is the result of lower sales for the 2005 period.

For the first quarter of 2005, the Company posted a loss of $910,560, or $.29
per share, compared to a loss of $267,456, or $.09 per share, for the same
period of 2004. This increased loss amounted to $643,104 and was primarily the
result of decreased sales. For the first quarter of 2005, the Company's general
and administrative costs totaled $1,869,752, a slight decrease from the first
quarter of 2004.

Interest

Interest expense amounted to approximately $121,000 and $163,000 for the first
quarters of 2005 and 2004, respectively. This decrease of $42,000 was primarily
the result of lower debt levels in 2005, and lower interest rates.

Liquidity and Capital Resources

As of March 31, 2005, the Company was in violation of certain provisions in its
credit agreement with Huntington National Bank, including covenant requirements
relating to tangible net worth, leverage ratio, and minimum fixed charge ratio
and, as a result, all debt obligations to Huntington are callable at March 31,
2005. The Company has not sought waiver of these covenant violations from
Huntington and the lender could elect to declare a default, rendering all
amounts outstanding immediately due and payable and terminating all commitments
to extend further credit. In the event of a declaration of default, if the
Company is unable to repay outstanding amounts the lender could proceed against
the collateral securing the indebtedness.

                    For The Three Months Ended March 31, 2005

Liquidity and Capital Resources (continued)

If Huntington declares a default or otherwise accelerates the payment of the
Company's obligations, there is no assurance that the Company's assets or cash
flow would be sufficient to repay the amounts due. As a result of these
circumstances, the Company has reflected all obligations to Huntington as
current liabilities, although the lender has not accelerated or demanded
payment. The Company continues to have frequent discussions with Huntington. The
relationship is cooperative, cordial and professional. The Company and
Huntington are currently discussing options, including additional equity
infusion, to alleviate the credit facility issues. The Company expects
Huntington to continue to extend the Company credit during this period of
resolving the credit issues.

In connection with the issuance of Series B Stock and related warrants, the
Company granted an option to purchase between 55,556 and 166,667 shares of
Series B-1 Stock and related common stock warrants for $9 per preferred share
and warrant unit. This option grant was approved on January 19, 2005 by the
Company's stockholders pursuant to certain NASD rules providing for qualitative
listing requirements applicable to securities traded on the NASDAQ National
Market and NASDAQ SmallCap Market.

Immediately after approval by the stockholders of the Company, the note was
automatically converted into 166,667 shares of Series B-1 Stock (calculated at a
price of $9.00 per share) that were issued to the Investor; and the Company also
issued a warrant to purchase 125,000 shares of Common Stock at a price of $3.00
per share to the Investor. Each outstanding share of Series B-1 Stock is
convertible into three shares of Common Stock. In addition, the shares of Series
B-1 Stock have conversion, redemption, and voting rights identical to those of
the shares of Series B Stock

For 2005, anticipated working capital requirements are expected to be met from
the cash flow from operations and the sale of one or more of the Company's
manufacturing facilities. At December 31, 2004, there were no material
commitments for capital expenditures for the ensuing year beyond the Company's
normal tooling and line maintenance requirements.

Item 3.         QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET
                RISK

We are exposed to the impact of interest rate changes and, to a lesser extent,
foreign currency fluctuations. We have not entered into interest rate
transactions for speculative purposes or otherwise. Our foreign currency
exposures were immaterial as of March 31, 2005. Our primary interest rate risk
exposure has resulted from floating rate debt related to our revolving loan
facility and would be immaterial to our results from operations if rates were to
increase 1% from March 31, 2005 rates. We currently do not hedge our exposure to
floating interest rate risk.

Item 4.         CONTROLS AND PROCEDURES

(a) EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES.

Our Chief Executive Officer and Chief Financial Officer have concluded, based on
their evaluation as of March 31, 2005, that the Company's disclosure controls
and procedures were not effective during the quarter-ended March 31, 2005.

This determination was made because of our Chief Executive Officer and Chief
Financial Officer's belief that the Company's resources have been insufficient
to address its financial reporting requirements in a timely fashion during
recent periods. The Company has had to extend the filing deadlines for it's
fiscal year 2004 Form 10-K, its fiscal year 2003 Form 10-K, its September 30,
2003 Form 10-Q and three of its fiscal year 2004 Form 10-Qs because it lacked
the resources to address the financial reporting related to significant and
complex business transactions.

In particular, the Company has suffered from insufficient personnel resources.
Additionally, the Company has struggled with complying with the increased
reporting requirements that have resulted from the Sarbanes-Oxley Act and new
National Association of Security Dealers rules. Areas of the Company's internal
controls and procedures that are insufficient include inventory quantity
determination, inventory valuation, revenue recognition, warranty obligations,
controls over fair value of equity securities, basic controls over the accuracy
of general ledger information and controls over accounting for income taxes and
required disclosure. Certain of these areas were recently brought to our
attention by the Company's auditors and we are currently assessing these areas.
The Company's internal controls and procedures are also ineffective in ensuring
that material information relating to the Company is made known to the Chief
Executive Officer and Chief Financial Officer by others within the Company.

Specifically, our independent auditors have advised the Company that internal
controls over the following aspects of the Company's accounting are insufficient
or non-existent and represent reportable conditions that they believe to be
material weaknesses: inventory quantity determination, inventory valuation,
revenue recognition, warranty obligations, controls over fair value of equity
securities, basic controls over the accuracy of general ledger information and
controls over accounting for income taxes and required disclosure.

                     TRANS-INDUSTRIES, INC. AND SUBSIDIARIES

Item 4. Controls & Procedures (continued)

The Company reported in its September 30, 2004 Form 10-Q that as a part of its
evaluation of internal controls and procedures, it expected that Company
personnel would have additional time to devote to financial reporting in the
fourth quarter of 2004, that an employee was added to the Company's staff
responsible for compliance with reporting obligations in November 2004, and that
the Company expected that its disclosure controls and procedures would be fully
effective during the fourth quarter of 2004 or soon thereafter. However, the
additional staff and employee time was insufficient to provide the company with
necessary resources to adequately address its internal controls and procedures.
In addition, Company staff utilized additional time to adjust to the procedures
of its new auditor.

The Company, including its new Chief Executive Officer appointed on March 16,
2005, is continuing to evaluate its resources for addressing its financial
reporting and making appropriate changes to provide sufficient resources and
time to prepare and file periodic reports within the time periods specified in
the SEC's rules and regulations and provide for reviews by management, the Audit
Committee and the Board of Directors. Our Chief Executive Officer and Chief
Financial Officer are, in connection with the evaluation, reviewing our
personnel, resources and disclosure controls and procedures. The evaluation is
intended to lead to changes that will ensure that our disclosure controls are
effective at a reasonable assurance level. Specifically, the evaluation is aimed
at ensuring that our disclosure controls are effective for gathering, analyzing
and disclosing in a timely manner the information we are required to disclose in
our reports filed under the Securities Exchange Act of 1934. In addition, the
Company was able to timely file this Form 10-Q and expects to timely file
future periodic reports.

(b) CHANGES IN INTERNAL CONTROLS

There were no changes in the Company's internal controls over financial
reporting that occurred during our last fiscal quarter that have materially
affected, or are reasonably likely to materially affect, the Company's internal
control over financial reporting. However, as noted above, the Company has
taken, and is continuing to take, certain actions designed to enhance the
Company's internal control over financial reporting and its disclosure controls
and procedures.
