verify the acceptance and execute a book-entry delivery to the Exchange Agent's
account at DTC. DTC will then send an Agent's message to the Exchange Agent for
its acceptance. Delivery of the Agent's Message by DTC will satisfy the terms of
the Exchange Offer as to execution and delivery of a Letter of Transmittal by
the participant identified in the Agent's Message. DTC participants may also

ATOP.

Ladies and Gentlemen:

     By execution hereof, the undersigned acknowledges receipt of the
Prospectus, dated May , 1998 (as the same may be amended from time to time, the
"Prospectus" and, together with this Letter of Transmittal, the "Exchange
Offer"), of Eagle-Picher Industries, Inc., an Ohio corporation (the "Company")
and this Letter of Transmittal and the instructions hereto, which together
constitute Company's offer to exchange $1,000 principal amount of its 9 3/8%
Senior Notes due 2008 (the "Exchange Notes") of the Company, upon the terms and
subject to the conditions set forth in The Exchange Offer, for each $1,000
principal amount of their outstanding 9 3/8% Senior Notes due 2008 (the "Initial
Notes").

     Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to the Company the principal amount of Initial Notes
indicated above. Subject to, and effective upon, the acceptance for exchange of
the Initial Notes tendered herewith, the undersigned hereby exchanges, assigns
and transfers to, or upon the order of, the Company all right, title and
interest in and to such Initial Notes. The undersigned hereby irrevocably
constitutes and appoints the Exchange Agent as the true and lawful agent and
attorney-in-fact of the undersigned (with full knowledge that the Exchange Agent
also acts as the agent of the Company) with respect to such Initial Notes with
full power of substitution (such power-of-attorney being deemed to be an
irrevocable power coupled with an interest) to (i) present such Initial Notes
and all evidences of transfer and authenticity to, or transfer ownership of,
such Initial Notes on the account books maintained by the Book-Entry Transfer
Facility to, or upon the order of, the Company, (ii) present such Initial Notes
for transfer of ownership on the books of the Company or the trustee under the
Indenture (the "Trustee") and (iii) receive all benefits and otherwise exercise
all rights of beneficial ownership of such Initial Notes, all in accordance with
the terms and conditions of the Exchange Offer as described in the Prospectus.

     The undersigned represents and warrants that it has full power and
authority to tender, exchange, assign and transfer the Initial Notes tendered
hereby and to acquire Exchange Notes issuable upon the exchange of such tendered
Initial Notes, and that, when the same are accepted for exchange, the Company
will acquire good and unencumbered title to the tendered Initial Notes, free and
clear of all liens, restrictions, charges and encumbrances and not subject to
any adverse claim or right. The undersigned also warrants that it will, upon
request, execute and deliver any additional documents deemed by the Exchange
Agent or the Company to be necessary or desirable to complete the exchange,
assignment and transfer of the Initial Notes tendered hereby or transfer
ownership of such Initial Notes on the account books maintained by the
book-entry transfer facility.

     The Exchange Offer is subject to certain conditions as set forth in the
Prospectus under the caption "The Notes Exchange Offer--Conditions." The
undersigned recognizes that as a result of these conditions (which may be waived
by the Company, in whole or in part, in the reasonable discretion of the
Company), as more particularly set forth in the Prospectus, the Company may not
be required to exchange any of the Initial Notes tendered hereby and, in such
event, the Initial Notes not exchanged will be returned to the undersigned at
the address shown above.

     THE EXCHANGE OFFER IS NOT BEING MADE TO ANY BROKER-DEALER WHO PURCHASED
INITIAL NOTES DIRECTLY FROM THE COMPANY FOR RESALE PURSUANT TO RULE 144A UNDER
THE SECURITIES ACT OR ANY PERSON THAT IS AN "AFFILIATE" OF THE COMPANY OR
EAGLE-PICHER HOLDINGS, INC. ("PARENT") WITHIN THE MEANING OF RULE 405 UNDER THE
SECURITIES ACT. THE UNDERSIGNED UNDERSTANDS AND AGREES THAT THE COMPANY RESERVES
THE RIGHT NOT TO ACCEPT TENDERED INITIAL NOTES FROM ANY TENDERING HOLDER IF THE
COMPANY DETERMINES, IN ITS REASONABLE DISCRETION, THAT SUCH ACCEPTANCE COULD
RESULT IN A VIOLATION OF APLICABLE SECURITIES LAWS.

     The undersigned, if the undersigned is a beneficial holder, represents (or,
if the undersigned is a broker, dealer, commercial bank, trust company or other
nominee, represents that it has received representations from the beneficial
owners of the Initial Notes (the "Beneficial Owner") stating) that, (i) the
Exchange Notes to be acquired in connection with the Exchange Offer by the
Holder and each Beneficial Owner of the Initial Notes

                                       5










are being acquired by the Holder and each such Beneficial Owner in the ordinary
course of their business, (ii) the Holder and each such Beneficial Owner are not
engaged in, do not intend to engage in, and have no arrangement or understanding
with any person to participate in, a distribution of the Exchange Notes, (iii)
the Holder and each Beneficial Owner acknowledge and agree that any person
participating in the Exchange Offer for the purpose of distributing the Exchange
Notes cannot rely on the interpretations of the staff of the Commission
discussed in the Prospectus under the caption "The Notes Exchange Offer--Purpose
and Effect of the Notes Exchange Offer" and may only sell the Exchange Notes
acquired by such person pursuant to a registration statement containing the
selling securityholder information required by Item 507 of Regulation S-K under
the Securities Act, (iv) if the Holder is a broker-dealer that acquired Initial
Notes as a result of market-making activities or other trading activities, it
will deliver a prospectus in connection with any resale of Exchange Notes
acquired in the Exchange Offer (but by so acknowledging and by delivering a
prospectus, the undersigned will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act) and (v) neither the
Holder nor any such Beneficial Owner is an "affiliate," as defined under Rule
405 of the Securities Act, of the Company or of Parent or is a broker-dealer who
purchased Initial Notes directly from the Company for resale pursuant to Rule
144A under the Securities Act.

     EACH BROKER-DEALER WHO ACQUIRED INITIAL NOTES FOR ITS OWN ACCOUNT AS A
RESULT OF MARKET-MAKING ACTIVITIES OR OTHER TRADING ACTIVITIES (A "PARTICIPATING
BROKER-DEALER"), BY TENDERING SUCH INTIAL NOTES AND EXECUTING THIS LETTER OF
TRANSMITTAL, AGREES THAT, UPON RECEIPT OF NOTICE FROM THE COMPANY OF THE
OCCURRENCE OF ANY EVENT OR THE DISCOVERY OF ANY FACT WHICH MAKES ANY STATEMENT
CONTAINED OR INCORPORATED BY REFERENCE IN THE PROSPECTUS UNTRUE IN ANY MATERIAL
RESPECT OR WHICH CAUSES THE PROSPECTUS TO OMIT TO STATE A MATERIAL FACT
NECESSARY IN ORDER TO MAKE THE STATEMENTS CONTAINED OR INCORPORATED BY REFERENCE
THEREIN, IN LIGHT OF THE CIRCUMSTANCES UNDER WHICH THEY WERE MADE, NOT
MISLEADING OR OF THE OCCURRENCE OF CERTAIN OTHER EVENTS SPECIFIED IN THE
REGISTRATION RIGHTS AGREEMENT, SUCH PARTICIPATING BROKER-DEALER WILL SUSPEND THE
SALE OF EXCHANGE NOTES PURSUANT TO THE PROSPECTUS UNTIL THE COMPANY HAS AMENDED
OR SUPPLEMENTED THE PROSPECTUS TO CORRECT SUCH MISSTATEMENT OR OMISSION AND HAS
FURNISHED COPIES OF THE AMENDED OR SUPPLEMENTED PROSPECTUS TO THE PARTICIPATING
BROKER-DEALER OR THE COMPANY HAS GIVEN NOTICE THAT THE SALE OF THE EXCHANGE
NOTES MAY BE RESUMED, AS THE CASE MAY BE.

     EACH PARTICIPATING BROKER-DEALER SHOULD CHECK THE BOX HEREIN UNDER THE
CAPTION "FOR PARTICIPATING BROKER-DEALERS ONLY" IN ORDER TO RECEIVE ADDITIONAL
COPIES OF THE PROSPECTUS, AND ANY AMENDMENTS AND SUPPLEMENTS THERETO, FOR USE IN
CONNECTION WITH RESALES OF THE EXCHANGE NOTES, AS WELL AS ANY NOTICES FROM THE
COMPANY TO SUSPEND AND RESUME USE OF THE PROSPECTUS. BY TENDERING ITS INITIAL
NOTES AND EXECUTING THIS LETTER OF TRANSMITTAL, EACH PARTICIPATING BROKER-DEALER
AGREES TO USE ITS REASONABLE BEST EFFORTS TO NOTIFY THE COMPANY OR THE EXCHANGE
AGENT WHEN IT HAS SOLD ALL OF ITS EXCHANGE NOTES. IF NO PARTICIPATING
BROKER-DEALERS CHECK SUCH BOX, OR IF ALL PARTICIPATING BROKER-DEALERS WHO HAVE
CHECKED SUCH BOX SUBSEQUENTLY NOTIFY THE COMPANY OR THE EXCHANGE AGENT THAT ALL
THEIR EXCHANGE NOTES HAVE BEEN SOLD, THE COMPANY WILL NOT BE REQUIRED TO
MAINTAIN THE EFFECTIVENESS OF THE EXCHANGE OFFER REGISTRATION STATEMENT OR TO
UPDATE THE PROSPECTUS AND WILL NOT PROVIDE ANY HOLDERS WITH ANY NOTICES TO
SUSPEND OR RESUME USE OF THE PROSPECTUS.

     The undersigned understands that tenders of the Initial Notes pursuant to
any one of the procedures described under "The Notes Exchange Offer--Procedures
for Tendering" in the Prospectus and in the

                                       6









instructions hereto will constitute a binding agreement between the undersigned
and the Company in accordance with the terms and subject to the conditions of
the Exchange Offer. All authority herein conferred or agreed to be conferred by
this Letter of Transmittal and every obligation of the undersigned hereunder
shall be binding upon the heirs, legal representatives, successors and assigns,
executors, administrators and trustees in bankruptcy of the undersigned and
shall survive the death or incapacity of the undersigned. Tendered Initial Notes
may be withdrawn at any time prior to 5:00 p.m. on the Expiration Date in
accordance with the terms of the Exchange Offer.

     The undersigned understands that by tendering Initial Notes pursuant to one
of the procedures described under "The Notes Exchange Offer--Procedures for
Tendering" in the Prospectus and the instructions hereto, the tendering Holder
will be deemed to have waived the right to receive any payment in respect of
interest on the Initial Notes accrued up to the date of issuance of the Exchange
Notes.

     The undersigned also understands and acknowledges that the Company reserves
the right in its sole discretion to purchase or make offers for any Initial
Notes that remain outstanding subsequent to the Expiration Date in the open
market, in privately negotiated transactions, through subsequent exchange offers
or otherwise. The terms of any such purchases or offers could differ from the
terms of the Exchange Offer.

     The undersigned understands that the delivery and surrender of the Initial
Notes is not effective, and the risk of loss of the Initial Notes does not pass
to the Exchange Agent, until receipt by the Exchange Agent of this Letter of
Transmittal, or a manually signed facsimile hereof, properly completed and duly
executed, with any required signature guarantees, together with all accompanying
evidences of authority and any other required documents in form satisfactory to
the Company. All questions as to form of all documents and the validity
(including time of receipt) and acceptance of tenders and withdrawals of Initial
Notes will be determined by the Company, in its sole discretion, which
determination shall be final and binding.

     Unless otherwise indicated herein in the box entitled "Special Issuance
Instructions," the undersigned hereby requests that any Initial Notes
representing principal amounts not tendered or not accepted for exchange be
issued in the name(s) of the undersigned and that Exchange Notes be issued in
the name(s) of the undersigned (or, in the case of Initial Notes delivered by
book-entry transfer, by credit to the account at the Book-Entry Transfer
Facility). Similarly, unless otherwise indicated herein in the box entitled
"Special Delivery Instructions," the undersigned hereby requests that any
Initial Notes representing principal amounts not tendered or not accepted for
exchange and Exchange Notes be delivered to the undersigned at the address(es)
shown above. The undersigned recognizes that the Company has no obligation
pursuant to the "Special Issuance Instructions" box or "Special Delivery
Instructions" box to transfer any Initial Notes from the name of the registered
Holder(s) thereof if the Company does not accept for exchange any of the
principal amount of such Initial Notes so tendered.

5.   SPECIAL ISSUANCE AND SPECIAL DELIVERY INSTRUCTIONS.

     Tendering Holders should indicate in the applicable box or boxes the name
and address to which Initial Notes for principal amounts not tendered or not
accepted for exchange or certificates for Exchange Notes, if applicable, are to
be issued or sent, if different from the name and address of the Holder signing
this Letter of Transmittal. In the case of payment to a different name, the
taxpayer identification or social security number of the person named must also
be indicated.

6.   TAXPAYER IDENTIFICATION NUMBER.

     Each tendering Holder is required to provide the Exchange Agent with the
Holder's social: security or Federal employer identification number, on
Substitute Form W-9 which is provided under "Important Tax Information" below,
or alternatively to establish another basis for exemption from backup
withholding. A Holder must cross out Item (2) in the Certification box in Part
III of Substitute Form W-9 if such Holder is subject to backup withholding.
Failure to provide the information on the form may subject such Holder to 31%
Federal backup withholding tax on any payment made to the Holder with respect to
the Exchange Offer. The appropriate box in Part I of Substitute Form W-9 should
be checked if the tendering or consenting Holder has not been issued a Taxpayer
Identification Number ("TIN") and has either applied for a TIN or intends to
apply for a TIN in the near future. If the box in Part I of Substitute Form W-9
is checked, the Holder should also sign the attached Certification of Awaiting
Taxpayer Identification Number. If the Exchange Agent is not provided with a TIN
within 60 days thereafter, the Exchange Agent will withhold 31% on all such
payments of the Exchange Notes until a TIN is provided to the Exchange Agent.

7.   TRANSFER TAXES.

     The Company will pay all transfer taxes applicable to the exchange and
transfer of lnitial Notes pursuant to the Exchange Offer, except if (i)
deliveries of certificates for Initial Notes for principal amounts not tendered
or not accepted for exchange are registered or issued in the name of any person
other than the Holder of

                                       13









Initial Notes tendered thereby, (ii) tendered certificates are registered in the
name of any person other than the person signing this Letter of Transmittal or
(iii) a transfer tax is imposed for any reason other than the exchange of
Initial Notes pursuant to the Exchange Offer, in which case the amount of any
transfer taxes (whether imposed on the registered Holder or any other persons)
will be payable by the tendering Holder. If satisfactory evidence of payment of
such taxes or exemption therefrom is not submitted herewith the amount of taxes
will be billed directly to such tendering Holder.

8.   IRREGULARITIES.

     All questions as to the form of all documents and the validity (including
time of receipt) and acceptance of all tenders and withdrawals of Initial Notes
will be determined by the Company, in its sole discretion which determination
shall be final and binding. ALTERNATIVE, CONDITIONAL OR CONTINGENT TENDERS OF
INITIAL NOTES WILL NOT BE CONSIDERED VALID. The Company reserves the absolute
right to reject any and all tenders of Initial Notes that are not in proper form
or the acceptance of which, in the Company's opinion, would be unlawful. The
Company also reserves the right to waive any defects, irregularities or
conditions of tender as to particular Initial Notes. The Company's
interpretations of the terms and conditions of the Exchange Offer (including the
instructions in this Letter of Transmittal) will be final and binding. Any
defect or irregularity in connection with tenders of Initial Notes must be cured
within such time as the Company determines, unless waived by the Company.
Tenders of Initial Notes shall not be deemed to have been made until all defects
or irregularities have been waived by the Company or cured. A defective tender
(which defect is not waived by the Company or cured by the Holder) will not
constitute a valid tender of Initial Notes and will not entitle the Holder to
Exchange Notes. None of the Company, the Trustee, the Exchange Agent or any
other person will be under any duty to give notice of any defect or irregularity
in any tender or withdrawal of any Initial Notes, or incur any liability to
Holders for failure to give any such notice.

9.   WAIVER OF CONDITIONS.

     The Company reserves the right, in its reasonable discretion, to amend or
waive any of the conditions to the Exchange Offer.

10.  MUTILATED, LOST, STOLEN OR DESTROYED CERTIFICATES FOR INITIAL NOTES.

     Any Holder whose certificates for Initial Notes have been mutilated, lost,
stolen or destroyed should write to or telephone the Trustee at the address or
telephone number set forth on the cover of this Letter of Transmittal for the
Exchange Agent.

11.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.

     Questions relating to the procedure for tendering Initial Notes and
requests for assistance or additional copies of the Prospectus, this Letter of
Transmittal, the Notice of Guaranteed Delivery or other documents may be
directed to the Exchange Agent, whose address and telephone number appear on the
cover of this Letter of Transmittal.

                            IMPORTANT TAX INFORMATION

     Under Federal income tax laws, a Holder who tenders Initial Notes prior to
receipt of the Exchange Notes is required to provide the Exchange Agent with
such Holder's correct TIN on the Substitute Form W-9 below or otherwise
establish a basis for exemption from backup withholding. If such Holder is an
individual, the TIN is his or her social security number. If the Exchange Agent
is not provided with the correct TIN, a $50 penalty may be imposed by the
Internal Revenue Service ("IRS") and payments, including any Exchange Notes,

                                       14









made to such Holder with respect to Initial Notes exchanged pursuant to the
Exchange Offer may be subject to backup withholding.

     Certain Holders (including among others, all corporations and certain
foreign persons) are not subject to these backup withholding and reporting
requirements. Exempt Holders should indicate their exempt status on the
Substitute Form W-9. A foreign person may qualify as an exempt recipient by
submitting to the Exchange Agent a properly completed IRS Form W-8 signed under
penalties of perjury, attesting to that Holder's exempt status. A Form W-8 can
be obtained from the Exchange Agent. See the enclosed "Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9" for
additional instructions. Holders are urged to consult their own tax advisors to
determine whether they are exempt.

     If backup withholding applies, the Exchange Agent is required to withhold
31% of any payments made to the Holder or other payee. Backup withholding is not
an additional Federal income tax. Rather, the Federal income tax liability of
persons subject to backup withholding will be reduced by the amount of tax
withheld. If withholding results in an overpayment of taxes, a refund may be
obtained from the IRS.

                         PURPOSE OF SUBSTITUTE FORM W-9

     To prevent backup withholding on payments, including any Exchange Notes,
made with respect to Initial Notes exchanged pursuant to the Exchange Offer, the
Holder is required to provide the Exchange Agent with (i) the Holder's correct
TIN by completing the form below, certifying that the TIN provided on the
Substitute Form W-9 is correct (or that such Holder is awaiting a TIN) and that
(A) such Holder is exempt from backup withholding, (B) the Holder has not been
notified by the IRS that the Holder is subject to backup withholding as a result
of failure to report all interest or dividends or (C) the IRS has notified the
Holder that the Holder is no longer subject to backup withholding, and (ii) if
applicable, an adequate basis for exemption.

WHAT NUMBER TO GIVE THE EXCHANGE AGENT

     The Holder is required to give the Exchange Agent the TIN (e.g., social
security number or employer identification number) of the registered Holder. If
the Initial Notes are held in more than one name or are held not in the name of
the actual owner, consult the enclosed "Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9" for additional guidance on which
number to report.

C. OBTAINING A NUMBER--If you do not have a taxpayer identification number or
you do not know your number, obtain Form SS-5, application for a Social Security
Number, or Form SS-4, Application for Employer Identification Number, at the
local office of the Social Security Administration or the Internal Revenue
Service and apply for a number.

D. PRIVACY ACT NOTICE--Section 6109 requires most recipients of dividend,
interest or other payments to give taxpayer identification numbers to payers who
must report the payments to the IRS. The IRS uses the numbers for identification
purposes.

     Payers must be given the numbers whether or not payees are required to file
tax returns. Payers must generally withhold 31% of taxable interest, dividend
and certain other payments to a payee who does not furnish a taxpayer
identification number. Certain penalties may also apply.

E.  PENALTIES--

     (1) Penalty for Failure to Furnish Taxpayer Identification Number. If you
fail to furnish your taxpayer identification number to a payer, you are subject
to a penalty of $50 for each such failure unless your failure is due to
reasonable cause and not to willful neglect.

     (2) Failure to Report Certain Dividend and Interest Payments. If you fail
to include any portion of an includable payment for interest, dividends, or
patronage dividends in gross income, such failure will be treated as being due
to negligence and will be subject to a penalty of 5% on any portion of an
under-payment attributable to that failure unless there is clear and convincing
evidence to the contrary.

     (3) Civil Penalty for False Information with Respect to Withholding. If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.

     (4) Criminal Penalty for Falsifying Information. Falsifying certifications
or affirmations may subject you to criminal penalties including fines and/or
imprisonment.
