Hexion Inc. Addresses Network Security Incident

Hexion Inc. (“Hexion” or the “company”) today announced it has taken
steps to restore its network and resume normal operations as quickly as
possible in response to a recent network security incident that
prevented access to certain systems and data within the company’s
network.

The company is currently implementing its technical recovery plan. When
it discovered the incident, Hexion immediately took aggressive steps to
isolate the issue by disabling certain systems and notifying the
appropriate government authorities. At the current time and throughout
the incident, the company’s manufacturing sites, which rely on different
networks, have continued to operate safely and with limited
interruption. The impact from the network security incident has
primarily impacted the company’s corporate functions.

Hexion has also taken additional precautionary measures to ensure the
continued safe operations of its sites. The company remains committed to
maintaining the network security with the least amount of customer
disruptions. A number of Hexion’s information technology systems,
including email correspondence, were immediately shut down to contain
the issue and continue to be restored.

Hexion is working closely with its customers and suppliers to minimize
any disruption. Hexion currently does not believe that any customer,
supplier or employee data was impacted as a result of this incident.

Forward Looking Statements

Certain statements in this press release are forward-looking statements
within the meaning of and made pursuant to the safe harbor provisions of
Section 27A of the Securities Act of 1933, as amended, and Section 21E
of the Securities Exchange Act of 1934, as amended. In addition, our
management may from time to time make oral forward-looking statements.
All statements, other than statements of historical facts, are
forward-looking statements. Forward-looking statements may be identified
by the words “believe,” “expect,” “anticipate,” “project,” “plan,”
“estimate,” “may,” “will,” “could,” “should,” “seek” or “intend” and
similar expressions. Forward-looking statements reflect our current
expectations and assumptions regarding our business, the economy and
other future events and conditions and are based on currently available

Actual results could vary materially depending on risks and
uncertainties that may affect our operations, markets, services, prices
and other factors as discussed in the Risk Factors section of our
filings with the Securities and Exchange Commission (the “SEC”). While
we believe our assumptions are reasonable, we caution you against
relying on any forward-looking statements as it is very difficult to
predict the impact of known factors, and it is impossible for us to
anticipate all factors that could affect our actual results. Important
factors that could cause actual results to differ materially from those
in the forward-looking statements include, but are not limited to, the
timing for resolving and any impact of the network security incident, a
weakening of global economic and financial conditions, interruptions in
the supply of or increased cost of raw materials, the loss of, or
difficulties with the further realization of, cost savings in connection
with our strategic initiatives, the impact of our substantial
indebtedness, our failure to comply with financial covenants under our
credit facilities or other debt, pricing actions by our competitors that
could affect our operating margins, changes in governmental regulations
and related compliance and litigation costs and the other factors listed
in our SEC filings. For a more detailed discussion of these and other
risk factors, see the Risk Factors section in our most recent Annual
Report on Form 10-K and Quarterly Report on Form 10-Q and our other
filings made with the SEC. All forward-looking statements are expressly
qualified in their entirety by this cautionary notice. The
forward-looking statements made by us speak only as of the date on which
they are made. Factors or events that could cause our actual results to
