J.P. Morgan Securities Inc.
277 Park Avenue
New York, New York 10172,
     As Representative of the several
     Underwriters listed in Schedule I
     hereto

Ladies and Gentlemen:

     SNPE, Inc. (the "Selling Stockholder"), the majority stockholder of Dynamic
Materials Corporation, a Delaware corporation (the "Company"), proposes to sell
to the several Underwriters listed in Schedule I hereto (the "Underwriters"),
for whom you are acting as representative (the "Representative"), an aggregate
of 5,153,897 shares (the "Underwritten Shares") and, at the option of the
Underwriters, up to an additional 773,085 shares (the "Option Shares"), of
common stock, par value $0.05 per share (the "Stock"), of the Company. The
Underwritten Shares and the Option Shares are herein referred to as the
"Shares."

     The Company and the Selling Stockholder hereby confirm their agreement with
the several Underwriters concerning the purchase and sale of the Shares, as
follows:

     1.   Registration Statement. The Company has prepared and filed with the
Securities and Exchange Commission (the "Commission") under the Securities Act
of 1933, as amended, and the rules and regulations of the Commission thereunder
(collectively, the "Securities Act"), a registration statement on Form S-3 (File
No.: 333-132748) including a prospectus (the "Basic Prospectus"), relating to
the Shares. The Company has also filed, or proposes to file, with the Commission
pursuant to Rule 424 under the Securities Act a prospectus supplement
specifically relating to the Shares (the "Prospectus Supplement"). The
registration statement, as amended at the time it became effective, including
the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the
Securities Act to be part of the registration statement at the time of its
effectiveness ("Rule 430 Information"), is referred to herein as the
"Registration Statement"; and as used herein, the term "Prospectus" means the
Basic Prospectus as supplemented by the Prospectus Supplement in the form first
used (or made available upon request of purchasers pursuant to Rule 173 under
the Securities Act) in connection with confirmation of sales of the Shares and
the term "Preliminary Prospectus" means each preliminary Prospectus Supplement
specifically relating to the Shares that omits Rule 430 Information included in
the Registration Statement together with the Basic Prospectus. If the Company
has filed an abbreviated registration statement pursuant to Rule 462(b) under
the Securities Act (the "Rule 462 Registration Statement"), then any reference
herein to the term "Registration Statement" shall

                                        2




be deemed to include such Rule 462 Registration Statement. Any reference in this
Agreement to the Registration Statement, any Preliminary Prospectus or the
Prospectus shall be deemed to refer to and include the documents incorporated by
reference therein pursuant to Item 12 of Form S-3 under the Securities Act, as
of the effective date of the Registration Statement or the date of such
Preliminary Prospectus or the Prospectus, as the case may be, and any reference
to "amend," "amendment" or "supplement" with respect to the Registration
Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer
to and include any documents filed after such date under the Securities Exchange
Act of 1934, as amended, and the rules and regulations of the Commission
thereunder (collectively, the "Exchange Act") that are deemed to be incorporated
by reference therein. Capitalized terms used but not defined herein shall have
the meanings given to such terms in the Registration Statement and the
Prospectus.

     At or prior to 7:00 A.M. (New York City time) on May 10, 2006 (the "Time of
Sale"), the Company had prepared the following information (collectively with
the pricing information set out on Schedule II, the "Time of Sale Information"):
a Preliminary Prospectus dated April 27, 2006, and each "free-writing
prospectus" (as defined pursuant to Rule 405 under the Securities Act) listed on
Schedule II hereto.

     2.   Purchase of the Shares by the Underwriters. (a) The Selling
Stockholder agrees to sell the Shares to the several Underwriters as provided in
this Agreement, and each Underwriter, on the basis of the representations,
warranties and agreements set forth herein and subject to the conditions set
forth herein, agrees, severally and not jointly, to purchase from the Selling
Stockholder at a purchase price per share of $33.3375 (the "Purchase Price") the
number of Underwritten Shares set forth opposite the name of such Underwriter in
Schedule I hereto.

     In addition, the Selling Stockholder agrees to sell the Option Shares to
the several Underwriters and the Underwriters shall have the option to purchase
at their election up to 773,085 Option Shares at the Purchase Price. Each
Underwriter, on the basis of the representations and warranties and agreements
herein contained and subject to the conditions set forth herein, shall have the
option to purchase, severally and not jointly, from the Selling Stockholder at
the Purchase Price that portion of the number of Option Shares as to which such
election shall have been exercised (to be adjusted by you so as to eliminate
fractional shares) determined by multiplying such number of Option Shares by a
fraction, the numerator of which is the number of Underwritten Shares as set
forth opposite such Underwriter's name on Schedule I, and the denominator of
which is the total number of Underwritten Shares set forth on Schedule I.

     The Underwriters may exercise the option to purchase the Option Shares at
any time, in whole or in part (but one time only), on or before the thirtieth
day following the date of this Agreement, by written notice from the
Representative to the Attorneys-in-Fact (as hereinafter defined). Such notice
shall set forth the aggregate number of Option Shares as to which the option is
being exercised and the date and time when the Option Shares are to be delivered
and paid for which may be the same date and time as the Closing Date (as
hereinafter defined) but shall not be earlier than the Closing Date nor later
than the tenth full business day after the date of such notice (unless such time
and date are postponed in accordance with the provisions of

                                        3




Section 12 hereof). Any such notice shall be given at least two business days
prior to the date and time of delivery specified therein.

     (b)  The Company and the Selling Stockholder understand that the
Underwriters intend to make a public offering of the Shares as soon after the
effectiveness of this Agreement as in the judgment of the Representative is
advisable, and initially to offer the Shares on the terms set forth in the
Prospectus. The Company and the Selling Stockholder acknowledge and agree that
the Underwriters may offer and sell Shares to or through any affiliate of an
Underwriter and that any such affiliate may offer and sell Shares purchased by
it to or through any Underwriter.

     (c)  Payment for the Shares shall be made by wire transfer in immediately
available funds to the U.S. bank account maintained by the Selling Stockholder
specified by the Attorneys-in-Fact to the Representative, in the case of the
Underwritten Shares, at the offices of Davis Polk & Wardwell, 450 Lexington
Avenue, New York, NY 10017 at 10:00 A.M. New York City time on May 15, 2006, or
at such other time or place on the same or such other date, not later than the
fifth business day thereafter, as the Representative and the Attorneys-in-Fact
may agree upon in writing or, in the case of each purchase of the Option Shares,
on the date and at the time and place specified by the Representative in the
written notice of the Underwriters' election to purchase such Option Shares. The
time and date of such payment for the Underwritten Shares is referred to herein
as the "Closing Date" and the time and date for each such payment for the Option
Shares, if other than the Closing Date, is herein referred to as an "Additional
Closing Date."

     Payment for the Shares to be purchased on the Closing Date or the
Additional Closing Date, as the case may be, shall be made against delivery to
the Representative for the respective accounts of the several Underwriters of
the Shares to be purchased on such date in definitive form registered in such
names and in such denominations as the Representative shall request in writing
not later than two full business days prior to the Closing Date or the
Additional Closing Date, as the case may be, with any transfer taxes payable in
connection with the sale of the Shares duly paid by the Selling Stockholder. The
certificates for the Shares will be made available for inspection and packaging
by the Representative at the office of J.P. Morgan Securities Inc. set forth
above not later than 1:00 P.M., New York City time, on the business day prior to
the Closing Date or the Additional Closing Date, as the case may be.

     (d)  Each of the Company and the Selling Stockholder acknowledges and
agrees that the Underwriters are acting solely in the capacity of an arm's
length contractual counterparty to the Selling Stockholder with respect to the
offering of Shares contemplated hereby (including in connection with determining
the terms of the offering) and not as a financial advisor or a fiduciary to, or
an agent of, the Company, the Selling Stockholder or any other person.
Additionally, neither the Representative nor any other Underwriter is advising
the Company, the Selling Stockholder or any other person as to any legal, tax,
investment, accounting or regulatory matters in any jurisdiction. The Company
and the Selling Stockholder shall consult with their own advisors concerning
such matters and shall be responsible for making their own independent
investigation and appraisal of the transactions contemplated hereby, and the
Underwriters shall

                                        4




have no responsibility or liability to the Company or the Selling Stockholder
with respect thereto. Any review by the Underwriters of the Company or the
Selling Stockholder, the transactions contemplated hereby or other matters
relating to such transactions will be performed solely for the benefit of the
Underwriters and shall not be on behalf of the Company or the Selling
Stockholder.

     3.   Representations and Warranties of the Company. The Company represents
and warrants to each Underwriter and the Selling Stockholder that:

     (a)  Preliminary Prospectus. No order preventing or suspending the use of
any Preliminary Prospectus has been issued by the Commission, and each

respect to any statements or omissions made in reliance upon and in conformity
with information relating to any Underwriter furnished to the Company in writing
by such Underwriter through the Representative expressly for use in such Time of

                                       26




writing; provided that the failure to notify the Indemnifying Person shall not
relieve it from any liability that it may have under this Section 9 except to
the extent that it has been materially prejudiced (through the forfeiture of
substantive rights or defenses) by such failure; and provided, further, that the
failure to notify the Indemnifying Person shall not relieve it from any

of such counsel shall be at the expense of such Indemnified Person unless (i)
the Indemnifying Person and the Indemnified Person shall have mutually agreed to
the contrary; (ii) the Indemnifying Person has failed within a reasonable time
to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the
Indemnified Person shall have reasonably concluded that there may be legal
defenses available to it that are different from or in addition to those
available to the Indemnifying Person; or (iv) the named parties in any such
proceeding (including any impleaded parties) include both the Indemnifying
Person and the Indemnified Person and representation of both parties by the same
counsel would be inappropriate due to actual or potential differing interests
between them. It is understood and agreed that the Indemnifying Person shall
not, in connection with any proceeding or related proceeding in the same
jurisdiction, be liable for the fees and expenses of more than one separate firm
(in addition to any local counsel) for all Indemnified Persons, and that all
such fees and expenses shall be paid or reimbursed as they are incurred. Any
such separate firm for any Underwriter, its affiliates, directors and officers
and any control persons of such Underwriter shall be designated in writing by
J.P. Morgan Securities Inc., any such separate firm for the Company, its
directors, its officers who signed the Registration Statement and any control
persons of the Company shall be designated in writing by the Company and any
such separate firm for the Selling Stockholder or its directors, officers or any
control persons shall be designated in writing by the Selling Stockholder. The
Indemnifying Person shall not be liable for any settlement of any proceeding
effected without its written consent, but if settled with such consent or if
there be a final judgment for the plaintiff, the Indemnifying Person agrees to
indemnify each Indemnified Person from and against any loss or liability by
reason of such settlement or judgment. Notwithstanding the foregoing sentence,
if at any time an Indemnified Person shall have requested that an Indemnifying
Person reimburse the Indemnified Person for fees and expenses of counsel as
contemplated by this subsection, the Indemnifying Person shall be liable for any
settlement of any proceeding effected without its written consent if (i) such
settlement is entered into more than 30 days after receipt by the Indemnifying
Person of such request and (ii) the Indemnifying Person shall not have
reimbursed the Indemnified Person in accordance with such request prior to the
date of such settlement. No Indemnifying Person shall, without the written
consent of the Indemnified Person, effect any settlement of any pending or
threatened proceeding in respect of which any Indemnified Person is or could
have been a party and indemnification could have been sought hereunder by such
Indemnified Person, unless such settlement (x) includes an unconditional release
of such Indemnified Person, in form and substance reasonably satisfactory to
such Indemnified Person, from all liability on claims that are the subject
matter of such

                                       27




proceeding and (y) does not include any statement as to or any admission of
fault, culpability or a failure to act by or on behalf of any Indemnified
Person.

     (f)  Contribution. If the indemnification provided for in subsections (a),
(b), (c) and (d) above is unavailable to an Indemnified Person or insufficient
in respect of any losses, claims, damages or liabilities referred to therein,
then each Indemnifying Person under such subsection, in lieu of indemnifying
such Indemnified Person thereunder, shall contribute to the amount paid or
payable by such Indemnified Person as a result of such losses, claims, damages
or liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company and the Selling Stockholder, on the one hand,
and the Underwriters, on the other, from the offering of the Shares or (ii) if
the allocation provided by clause (i) is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) but also the relative fault of the Company and the
Selling Stockholder, on the one hand, and the Underwriters, on the other, in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative benefits received by the Company and the Selling
Stockholder, on the one hand, and the Underwriters, on the other, shall be
deemed to be in the same respective proportions as the net proceeds (before
deducting expenses) received by the Selling Stockholder from the sale of the
Shares and the total underwriting discounts and commissions received by the
Underwriters in connection therewith, in each case as set forth in the table on
the cover of the Prospectus, bear to the aggregate offering price of the Shares.
The relative fault of the Company and the Selling Stockholder, on the one hand,
and the Underwriters, on the other, shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company and the Selling Stockholder or by the
Underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

     (g)  Limitation on Liability. The Company, the Selling Stockholder and the
Underwriters agree that it would not be just and equitable if contribution
pursuant to this Section 9 were determined by pro rata allocation (even if the
Underwriters were treated as one entity for such purpose) or by any other method
of allocation that does not take account of the equitable considerations
referred to in subsection (f) above. The amount paid or payable by an
Indemnified Person as a result of the losses, claims, damages and liabilities
referred to in subsection (f) above shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses incurred by such
Indemnified Person in connection with any such action or claim. Notwithstanding
the provisions of this Section 9, in no event shall an Underwriter be required
to contribute any amount in excess of the amount by which the total underwriting
discounts and commissions received by such Underwriter with respect to the
offering of the Shares exceeds the amount of any damages that such Underwriter
has otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Underwriters' obligations to contribute
pursuant to this Section 9 are several in proportion to their respective
purchase obligations hereunder and not joint.

                                       28




     (h)  Non-Exclusive Remedies. The remedies provided for in this Section 9
are not exclusive and shall not limit any rights or remedies which may otherwise
be available to any Indemnified Person at law or in equity.

     (i)  Further Limitation on Liability of the Selling Stockholder.
Notwithstanding anything to the contrary in this Section 9, the Selling
Stockholder shall have no obligation to pay any amount to the Underwriters under
this Section 9 until there shall have been a final court decision to the effect
that (x) the Registration Statement contained an untrue statement of a material
fact or omitted to state a material fact required to be stated therein or
necessary in order to make the statements therein not misleading or (y) the
Prospectus (or any amendment or supplement thereto), any Issuer Free Writing
Prospectus or any Time of Sale Information (including any Time of Sale
Information that has subsequently been amended) contained any untrue statement
of a material fact or omitted to state therein a material fact necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading (excluding, in each case (x) and (y), any such
untrue statement or omission made in reliance upon and in conformity with any
information relating to any Underwriter furnished to the Company in writing by
such Underwriter through the Representative expressly for use therein).

     10.  Effectiveness of Agreement. This Agreement shall become effective upon
the execution and delivery hereof by the parties.

     11.  Termination. This Agreement may be terminated in the absolute
discretion of the Representative, by notice to the Company and the Selling
Stockholder, if after the execution and delivery of this Agreement and prior to
the Closing Date or, in the case of the Option Shares, prior to the Additional
Closing Date (i) trading generally shall have been suspended or materially
limited on or by any of the New York Stock Exchange, the American Stock
Exchange, the National Association of Securities Dealers, Inc., The Nasdaq Stock
Market, Inc., or The NASDAQ Stock Market LLC; (ii) trading of any securities
issued or guaranteed by the Company shall have been suspended on any exchange or
in any over-the-counter market; (iii) a general moratorium on commercial banking
activities shall have been declared by federal or New York State authorities; or
(iv) there shall have occurred any outbreak or escalation of hostilities or any
change in financial markets or any calamity or crisis, either within or outside
the United States, that, in the judgment of the Representative, is material and
adverse and makes it impracticable or inadvisable to proceed with the offering,
sale or delivery of the Shares on the Closing Date or the Additional Closing
Date, as the case may be, on the terms and in the manner contemplated by this
Agreement, the Time of Sale Information and the Prospectus; provided that the
Representative shall not deliver such a notice pursuant to clause (i), (ii) or
(iv) based solely upon a suspension or limitation of trading prior to May 14,
2006 at the New York Stock Exchange, the American Stock Exchange, The Nasdaq
Stock Market, Inc., or The NASDAQ Stock Market LLC, that lasts no longer than
one hour and interferes with no more than a single day of trading, and that is
no longer in effect and does not interfere with the regularly scheduled opening
of trading on the New York Stock Exchange, the American Stock Exchange, The
Nasdaq Stock Market, Inc., or The NASDAQ Stock Market LLC on the next trading
day.

                                       29




     12.  Defaulting Underwriter. (a) If, on the Closing Date or the Additional
Closing Date, as the case may be, any Underwriter defaults on its obligation to
purchase the Shares that it has agreed to purchase hereunder on such date, the
non-defaulting Underwriters may in their discretion arrange for the purchase of
such Shares by other persons satisfactory to the Company and the Selling
Stockholder on the terms contained in this Agreement. If, within 36 hours after
any such default by any Underwriter, the non-defaulting Underwriters do not
arrange for the purchase of such Shares, then the Company and the Selling
Stockholder shall be entitled to a further period of 36 hours within which to
procure other persons satisfactory to the non-defaulting Underwriters to
purchase such Shares on such terms. If other persons become obligated or agree
to purchase the Shares of a defaulting Underwriter, either the non-defaulting
Underwriters or the Company and the Selling Stockholder may postpone the Closing
Date or the Additional Closing Date, as the case may be, for up to five full
business days in order to effect any changes that in the opinion of counsel for
the Company, counsel for the Selling Stockholder or counsel for the Underwriters
may be necessary in the Registration Statement and the Prospectus or in any
other document or arrangement, and the Company agrees to promptly prepare any
amendment or supplement to the Registration Statement and the Prospectus that
effects any such changes. As used in this Agreement, the term "Underwriter"
includes, for all purposes of this Agreement unless the context otherwise
requires, any person not listed in Schedule I hereto that, pursuant to this
Section 12, purchases Shares that a defaulting Underwriter agreed but failed to
purchase.

     (b)  If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by the non-defaulting
Underwriters, the Company and the Selling Stockholder as provided in subsection
(a) above, the aggregate number of Shares that remain unpurchased on the Closing
Date or the Additional Closing Date, as the case may be, does not exceed
one-eleventh of the aggregate number of Shares to be purchased on such date,
then the Company and the Selling Stockholder shall have the right to require
each non-defaulting Underwriter to purchase the number of Shares that such
Underwriter agreed to purchase hereunder on such date plus such Underwriter's
pro rata share (based on the number of Shares that such Underwriter agreed to
purchase on such date) of the Shares of such defaulting Underwriter or
Underwriters for which such arrangements have not been made.

     (c)  If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by the non-defaulting
Underwriters, the Company and the Selling Stockholder as provided in subsection
(a) above, the aggregate number of Shares that remain unpurchased on the Closing
Date or the Additional Closing Date, as the case may be, exceeds one-eleventh of
the aggregate amount of Shares to be purchased on such date, or if the Company
and the Selling Stockholder shall not exercise the right described in subsection
(b) above, then this Agreement or, with respect to any Additional Closing Date,
the obligation of the Underwriters to purchase Shares on the Additional Closing
Date, as the case may be, shall terminate without liability on the part of the
non-defaulting Underwriters. Any termination of this Agreement pursuant to this
Section 12 shall be without liability on the part of the Company and the Selling
Stockholder, except that the Company and the Selling Stockholder, as applicable,
will continue to be liable for the payment of expenses as set forth in Section
13 hereof and except that the provisions of Section 9 hereof shall not terminate
and shall remain in effect.

                                       30




     (d)  Nothing contained herein shall relieve a defaulting Underwriter of any
liability it may have to the Company, the Selling Stockholder or any
non-defaulting Underwriter for damages caused by its default.

     13.  Payment of Expenses. (a) Whether or not the transactions contemplated
by this Agreement are consummated or this Agreement is terminated, (A) except as
set forth in clause (B) of this subsection (a), the Selling Stockholder will pay
or cause to be paid all costs and expenses incident to the performance of its
and the Company's obligations hereunder, including without limitation, (i) the
costs incident to the authorization, issuance, sale, preparation and delivery of
the Shares and any taxes payable in that connection; (ii) the costs incident to
the preparation, printing and filing under the Securities Act of the
Registration Statement, the Preliminary Prospectus, any Issuer Free Writing
Prospectus, any Time of Sale Information and the Prospectus (including all
exhibits, amendments and supplements thereto) and the distribution thereof;
(iii) the costs of reproducing and distributing this Agreement; (iv) the fees
and expenses of the Company's counsel and independent accountants; (v) the fees
and expenses incurred in connection with the registration or qualification and
determination of eligibility for investment of the Shares under the laws of such
jurisdictions as the Representative may designate and the preparation, printing
and distribution of a Blue Sky Memorandum (including the related, reasonable
fees and expenses of counsel for the Underwriters); (vi) the cost of preparing
stock certificates; (vii) the costs and charges of any transfer agent, any
registrar and any Custodian; (viii) all expenses and application fees incurred
in connection with any filing with, and clearance of the offering by, the
National Association of Securities Dealers, Inc.; and (ix) all expenses incurred
by the Company in connection with any "road show" presentation to potential
investors; and (B) the Company shall pay or cause to be paid all costs and
expenses (including counsel fees) incident to the transfer of the listing of the
Stock from the Nasdaq Capital Market to the Nasdaq National Market.

     (b)  If (i) this Agreement is terminated pursuant to Section 11, (ii) the
Selling Stockholder for any reason fails to tender the Shares for delivery to
the Underwriters or (iii) the Underwriters decline to purchase the Shares for
any reason permitted under this Agreement, the Selling Stockholder agrees to
reimburse the Underwriters for all out-of-pocket costs and expenses (including
the fees and expenses of their counsel) reasonably incurred by the Underwriters
in connection with this Agreement and the offering contemplated hereby, up to a
maximum of $300,000.00.

     14.  Persons Entitled to Benefit of Agreement. This Agreement shall inure
to the benefit of and be binding upon the parties hereto and their respective
successors and the officers and directors and any controlling persons referred
to in Section 9 hereof. Nothing in this Agreement is intended or shall be
construed to give any other person any legal or equitable right, remedy or claim
under or in respect of this Agreement or any provision contained herein. No
purchaser of Shares from any Underwriter shall be deemed to be a successor
merely by reason of such purchase.

                                       31




     15.  Survival. The respective indemnities, rights of contribution,
representations, warranties and agreements of the Company, the Selling
Stockholder, and the Underwriters contained in this Agreement or made by or on
behalf of the Company, the Selling Stockholder, or the Underwriters pursuant to
this Agreement or any certificate delivered pursuant hereto shall survive the
delivery of and payment for the Shares and shall remain in full force and
effect, regardless of any termination of this Agreement or any investigation
made by or on behalf of the Company, the Selling Stockholder, or the
Underwriters.

     16.  Certain Defined Terms. For purposes of this Agreement, (a) except
where otherwise expressly provided, the term "affiliate" has the meaning set
forth in Rule 405 under the Securities Act; (b) the term "business day" means
any day other than a day on which banks are permitted or required to be closed
in New York City; (c) the term "subsidiary" has the meaning set forth in Rule
405 under the Securities Act; and (d) the term "significant subsidiary" has the
meaning set forth in Rule 1-02 of Regulation S-X under the Exchange Act.

     17.  Miscellaneous. (a) Authority of the Representative. Any action by the
Underwriters hereunder may be taken by J.P. Morgan Securities Inc. on behalf of
the Underwriters, and any such action taken by J.P. Morgan Securities Inc. shall
be binding upon the Underwriters.

     (b)  Notices. All notices and other communications hereunder shall be in
writing and shall be deemed to have been duly given if mailed or transmitted and
confirmed by any standard form of telecommunication. Notices to the Underwriters
shall be given to the Representative J.P. Morgan Securities Inc., 277 Park

Vice President.

     (c)  Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York.

     (d)  Submission to Jurisdiction. Each of the Company and the Selling
Stockholder irrevocably agrees that any legal suit, action or proceeding arising
out of or based upon this Agreement or the transactions contemplated hereby
("Related Proceedings") may be instituted in the federal courts of the United
States of America located in the City of New York or the courts of the State of
New York in each case located in the Borough of Manhattan in the City of New
York (collectively, the "Specified Courts"), and irrevocably submits to the
non-exclusive jurisdiction of such courts in any such suit, action or
proceeding. Each of the Company and the Selling Stockholder further agrees that
service of any process, summons, notice or document by mail to its address set
forth above shall be effective service of process for any lawsuit, action or
other proceeding brought in any such court. The Company has appointed CT
Corporation, 111 Eighth Avenue, 13th Floor, New York, NY 10011, Attn: Tim Carney
and the Selling Stockholder has appointed Phillips Nizer LLP, 666 Fifth Avenue,
New York, NY 10103, Attn: Stephen Kramer

                                       32




(each an "Authorized Agent") as its authorized agent in the Borough of Manhattan
in The City of New York upon which process may be served in any such suit,
action or proceeding relating to this Agreement, and agrees that service of
process upon such agent, and written notice of said service by the person
serving the same to the address provided in subsection (b) above, shall be
deemed in every respect effective service of process in any such suit, action or
proceeding. Each of the Company and the Selling Stockholder further agrees that,
in the event that its Authorized Agent shall at any time cease to be such duly
appointed and authorized agent for service of process, it shall take any and all
action as may be necessary to ensure that there shall be a duly appointed and
authorized agent for service of process in the Borough of Manhattan, The City of
New York. Each of the Company and the Selling Stockholder hereby irrevocably and
unconditionally waives any objection to the laying of venue of any lawsuit,
action or other proceeding in the Specified Courts, and hereby further
irrevocably and unconditionally waives and agrees not to plead or claim in any
such court that any such lawsuit, action or other proceeding brought in any such
court has been brought in an inconvenient forum.

     With respect to any Related Proceedings, each of the Company and the
Selling Stockholder irrevocably waives, to the fullest extent permitted by
applicable law, all immunity (whether on the basis of sovereignty or otherwise)
from jurisdiction, service of process, attachment (both before and after
judgment) and execution to which it might otherwise be entitled in the Specified
Courts, and with respect to any judgment by Specified Court ("Related
Judgment"), each of the Company and the Selling Stockholder waives any such
immunity in the Specified Courts or any other court of competent jurisdiction,
and will not raise or claim or cause to be pleaded any such immunity at or in
respect of any such Related Proceeding or Related Judgment, including, without
limitation, any immunity pursuant to the United States Foreign Sovereign
Immunities Act of 1976, as amended.

Underwriter to serve process in any other manner permitted by law or to bring
any suit, action or proceeding in any other jurisdiction.

include counterparts delivered by any standard form of telecommunication), each

the same instrument.

Agreement, nor any consent or approval to any departure therefrom, shall in any
event be effective unless the same shall be in writing and signed by the parties

             Form of Opinion of LeBoeuf, Lamb, Greene & MacRae LLP

     (1)  The Registration Statement was declared effective under the Securities
Act as of the date and time specified in such opinion; each of the Preliminary
Prospectus and the Prospectus was filed with the Commission pursuant to the
subparagraph of Rule 424(b) under the Securities Act specified in such opinion
on the date specified therein; and no stop order suspending the effectiveness of
the Registration Statement or any post-effective amendment thereof or the use of
the Prospectus, the Time of Sale Information or any "issuer free writing
prospectus" (as defined in Rule 433 under the Securities Act) relating to the
Shares has been issued and no proceeding for that purpose or pursuant to Section
8A of the Securities Act against the Company or in connection with the offering
is pending or, to the knowledge of such counsel, threatened by the Commission.
All filings required by Rule 424(b) under the Securities Act with respect to the
Registration Statement have been made.

with officers and representatives of the Company, representatives of the
independent public accountants for the Company and the Underwriters at which the
contents of the Registration Statement, the Time of Sale Information and the
Prospectus and any amendment and supplement thereto and related matters were
discussed and, no facts have come to such counsel's attention that have caused
such counsel to believe that (i) the Registration Statement, at the time the
Registration Statement became effective, contained an untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements therein not misleading, (ii) the Time of
Sale Information, at the Time of Sale (which such counsel may assume to be the
date of the Underwriting Agreement) contained any untrue statement of a material
fact or omitted to state a material fact necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading, or (iii) the Prospectus or any amendment or supplement thereto, as
of its date, contained, or as of the Closing Date contains, an untrue statement
of a material fact or omitted, as of its date, or as of the Closing Date omits,
to state a material fact necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading (it being
understood that with respect to each of the foregoing, such counsel need not
express any comment with respect to the financial statements and notes thereto
or the related statements, supporting schedules and other financial and
accounting information included, incorporated by reference or referred to
therein or omitted therefrom).

     In rendering such opinion, such counsel may rely as to matters of fact on
certificates of responsible officers of the Company and public officials that
are furnished to the Underwriters.

     The opinion of counsel described above shall be rendered to the
Underwriters at the request of the Company and shall so state therein.

                                                                         Annex B

             Form of Opinion of Orrick, Herrington & Sutcliffe LLP

     (1)  The execution and delivery of the Power of Attorney, the Underwriting
Agreement and the Custody Agreement and the sale and delivery of the Shares by
the Selling Stockholder and the consummation by the Selling Stockholder of the
transactions contemplated in the Underwriting Agreement and performance by the
Selling Stockholder of its obligations under the Underwriting Agreement have
been duly authorized by all necessary action on the part of the Selling
Stockholder. The Power of Attorney, the Underwriting Agreement and the Custody
Agreement have been duly executed and delivered by or on behalf of the Selling
Stockholder. The Power of Attorney and the Custody Agreement are valid and
binding on the Selling Stockholder in accordance with their respective terms.

     (2)  If an Underwriter simultaneously (A) acquires possession in the State
of New York of the security certificates representing the applicable
Certificated Securities, indorsed to such Underwriter or in blank by an
effective indorsement, (B) gives value, and (C) does not have notice of any
adverse claim to any such Certificated Security, then such Underwriter will
acquire its interest in such Certificated Securities free of any adverse claim.

     (3)  If the Depository Trust Company ("DTC") on the Closing Date or the
Additional Closing Date, as applicable (A) was a clearing corporation, (B)
acquired possession in the State of New York of the security certificates
representing the DTC Securities, indorsed to DTC or in blank by an effective
indorsement, or registered in the name of DTC, upon original issue or
registration of transfer by the Company, (C) established a security entitlement
to the DTC Securities in favor of an entitlement holder, and (D) did not have
notice of any adverse claim to any DTC Security, then on the Closing Date or the
Additional Closing Date, as applicable, DTC acquired its interest in the DTC
Securities free of any adverse claim.

     (4)  If DTC is a clearing corporation and indicates by book entry that the
applicable DTC Securities have been credited to an Underwriter's securities
account, then such Underwriter will acquire a security entitlement with respect
to such DTC Securities. If such Underwriter acquires such security entitlement
for value and without notice of any adverse claim, then an action based on an
adverse claim to such DTC Securities, whether framed in conversion, replevin,
constructive trust, equitable lien, or other theory, may not be asserted against
such Underwriter.

     (5)  Upon the execution and delivery of the Underwriting Agreement, Section
17(d) of the Underwriting Agreement shall be valid, binding and enforceable
against the Selling Stockholder in accordance with terms set forth therein.

     (6)  No consent, approval, authorization or order of, nor any filing with,
any court or governmental agency or body is required for the consummation by the
Selling Stockholder of the transactions contemplated in the Underwriting
Agreement and the Custody Agreement, except such as may have been obtained or
made under the Securities Act and such as may be required under the blue sky
laws of any jurisdiction in connection with the purchase and distribution of

                                       41




the Shares by the Underwriters (as to which counsel need not express any
opinion). Counsel need not express any opinion as to matters of French law.

     (7)  Neither the sale of the Shares by the Selling Stockholder pursuant to
the Underwriting Agreement, nor the performance by the Selling Stockholder of
the obligations set forth in the Underwriting Agreement have resulted and will
not, as of the date hereof, result in (i) any violation of, conflict with or
default under (A) the Certificate or the Bylaws of the Selling Stockholder, (B)
any judgment, decree or order applicable to the Selling Stockholder and known to
such counsel or (C) to counsel's knowledge, any statute, rule or governmental
regulation applicable to the Selling Stockholder or (ii) any material violation
of, material conflict with or material default under any agreement or instrument
to which the Selling Stockholder is a party or by which it is bound known to
such counsel.

     In rendering such opinion, such counsel may rely as to matters of fact on
certificates of responsible officers of the Selling Stockholder and public
officials that are furnished to the Underwriters.

     The opinion of counsel described above shall be rendered to the
Underwriters at the request of the Selling Stockholder and shall so state
therein.

Re:  Dynamic Materials Corporation - Public Offering

Ladies and Gentlemen:

     The undersigned understands that you, as Representative of the several

Notwithstanding the foregoing, if (1) during the last 17 days of the 90 day

material event relating to the Company occurs; or (2) prior to the expiration of

90-day period, the restrictions imposed by this Letter Agreement shall continue
to apply until the expiration of the 18-day period beginning on the issuance of

     In furtherance of the foregoing, the Company, and any duly appointed
transfer agent for the registration or transfer of the securities described

such transfer would constitute a violation or breach of this Letter Agreement.

     The undersigned hereby represents and warrants that the undersigned has
full power and authority to enter into this Letter Agreement. All authority
herein conferred or agreed to be conferred and any obligations of the
undersigned shall be binding upon the successors, assigns, heirs or personal
representatives of the undersigned.

     The undersigned understands that, if the Underwriting Agreement does not
become effective, or if the Underwriting Agreement (other than the provisions
thereof which survive termination) shall terminate or be terminated prior to
payment for and delivery of the Common Stock to be sold thereunder, the
undersigned shall be released from all obligations under this Letter Agreement.
The undersigned understands that the Underwriters are entering into the
Underwriting Agreement and proceeding with the Public Offering in reliance upon
this Letter Agreement.

     This Letter Agreement shall be governed by and construed in accordance with
the laws of the State of New York, without regard to the conflict of laws
principles thereof.

                                        Very truly yours,
