       Dynasil Corporation of America Fails to Meet Financial Covenants
                           in Loan Agreements

                    Delays filing Annual Report on Form 10-K
                       Pursuant to Form 12b-25 Extension

Watertown, MA, December 31, 2012   Dynasil Corporation of America (NASDAQ: DYSL)
today announced that the Company has failed to comply with the financial
covenants set forth in the terms of its outstanding indebtedness for its fiscal
fourth quarter ended September 30, 2012.  These covenants require the Company
to maintain specified ratios of earnings before interest, taxes, depreciation
and amortization (EBITDA) to fixed charges and to total/senior debt.

The Company continues to be current with all principal and interest payments due
on all its outstanding indebtedness and management expects to continue
discussions with its lenders to address the financial covenant situation.

These financial covenant defaults give the lenders the right to
accelerate the maturity of the indebtedness outstanding and
foreclose on any security interest. Furthermore, Sovereign Bank, N.A,
the Company's senior lender, may, at its option, impose a default interest
rate with respect to the senior debt outstanding, which is 5% higher
than the rate otherwise in effect. To date, the
lenders have not taken any such actions. However, the Company cannot predict
when or whether a resolution of this situation will be achieved.

As of September 30, 2012, the Company had total indebtedness outstanding of
approximately $12.0 million, consisting of approximately $9.0 million of senior
debt owed to Sovereign Bank and approximately $3.0 million of subordinated debt
owed to Massachusetts Capital Resources Company. The Company's indebtedness is
secured by substantially all the accounts and assets of the Company and is
guaranteed by its subsidiaries.



The causes for the covenant violations are lower revenue and higher than
expected expenses  in the Company's Dynasil Products and RMD divisions during
the fiscal quarter ended September 30, 2012, combined with the continued
investment in Dynasil Biomedical Corp. and the Company's Dual Mode nuclear
detection initiative. In addition, the Company incurred a significant, non-
recurring charge of approximately $466,000 to its selling, general and
administrative expenses during that quarter related to costs incurred as a
result of a review, under the direction of the Audit Committee of the Board, of
certain cash application processes and billing practices of the RMD division.
This investigation has been completed and has resulted in modifications in the
division's practices and internal controls.  The Company does not anticipate
additional expenses for this matter.

The Company has recently taken and will continue to take actions to improve its
liquidity, including the implementation of a number of initiatives designed to
conserve cash, optimize profitability and right-size the cost structure of its
various businesses.  The Company has retained Argus Management Corporation and
expects to engage an investment bank as financial advisors to assist it in
evaluating strategic and restructuring alternatives.

However, because of the uncertainty of any resolution of the covenant
violations and possibility of an acceleration of the indebtedness by the
lenders, the Company will reclassify all of its outstanding indebtedness as a
current liability when it reports its results for the fiscal year ended
September 30, 2012. As a result, the Company's independent registered public
accountants, McGladrey LLP, will include a "going concern" qualification in its
audit opinion with respect to such financial statements.  Furthermore, as a
result of the decline in the fair value of certain business operations, the
Company expects it will record significant non-cash goodwill and long-lived
asset impairment charges as of September 30, 2012, though at this time it is
unable to provide any estimate of such impairment charges.

The Company plans to file a Notification of Late Filing on Form 12b-25 with
the SEC on January 2, 2013 that will allow the Company to extend the deadline
to file its Annual Report on Form 10-K by 15 calendar days.  The Company has
taken this step in order to have more time to finalize the preparation of its
financial statements for the fiscal year ended September 30, 2012 and
complete the audit process.  With this extension, the Company's Form 10-K
will be deemed timely filed if it is filed not later January 15, 2013. The
Company intends to file the Form 10-K as soon as practicable.
