The undersigned hereby tenders to HC Corporation, a Delaware corporation (the "Purchaser"), the above described shares of Class A common stock, par value $0.01 per share (together with the associated preferred share purchase rights, the "Shares"), of Hawk Corporation, a Delaware corporation ("Hawk"), pursuant to the Purchaser's offer to purchase all of the outstanding Shares, at a purchase price of $50.00 per Share (the "Offer Price"), net to the seller in cash, without interest and less any applicable withholding taxes, upon the terms and subject to the conditions set forth in the Offer to Purchase dated November 1, 2010 (as it may be amended or supplemented, the "Offer to Purchase"), and in this Letter of Transmittal, as it may be amended or supplemented (which, together with the Offer to Purchase, constitute the "Offer").

Upon the terms and subject to the conditions of the Offer (and if the Offer is extended or amended, the terms of any such extension or amendment), and effective upon acceptance for payment of the Shares tendered herewith in accordance with the terms of the Offer, the undersigned hereby sells, assigns and transfers to or upon the order of the Purchaser all right, title and interest in and to all of the Shares that are being tendered hereby (and any and all dividends, distributions, rights, other Shares or other securities issued or issuable in respect thereof on or after the date hereof (collectively, "Distributions")) and irrevocably constitutes and appoints Citibank, N.A. (the "Depositary") the true and lawful agent and attorney-in-fact of the undersigned with respect to such Shares (and any and all Distributions), with full power of substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest), to (i) deliver certificates for such Shares (and any and all Distributions) or transfer ownership of such Shares (and any and all Distributions) on the account books maintained by DTC, together, in any such case, with all accompanying evidences of transfer and authenticity, to or upon the order of the Purchaser, (ii) present such Shares (and any and all Distributions) for transfer on the books of Hawk and (iii) receive all benefits and otherwise exercise all rights of beneficial ownership of such Shares (and any and all Distributions), all in accordance with the terms of the Offer. By tendering Shares in accordance with the procedures set forth herein, the undersigned also tenders the preferred stock purchase rights associated with such Shares.

By executing this Letter of Transmittal, the undersigned hereby irrevocably appoints each of the designees of the Purchaser the attorneys-in-fact and proxies of the undersigned, each with full power of substitution, (i) to vote at any annual or special meeting of Hawk's stockholders or any adjournment or postponement thereof or otherwise in such manner as each such attorney-in-fact and proxy or its, his or her substitute shall in its, his or her sole discretion deem proper with respect to, (ii) to execute any written consent concerning any matter as each such attorney-in-fact and proxy or its, his or her substitute shall in its, his or her sole discretion deem proper with respect to and (iii) to otherwise act as each such attorney-in-fact and proxy or its, his or her substitute shall in its, his or her sole discretion deem proper with respect to all of the Shares (and any and all Distributions) tendered hereby and accepted for payment by the Purchaser. This appointment will be effective if and when, and only to the extent that, the Purchaser accepts such Shares for payment pursuant to the Offer. This power of attorney and proxy are irrevocable and are granted in consideration of the acceptance for payment of such Shares in accordance with the terms of the Offer. Such acceptance for payment shall, without further action, revoke any prior powers of attorney and proxies granted by the undersigned at any time with respect to such Shares (and any and all Distributions), and no subsequent powers of attorney, proxies, consents or revocations may be given by the undersigned with respect thereto (and, if given, will not be deemed effective). The Purchaser reserves the right to require that, in order for the Shares to be deemed validly tendered, immediately upon the Purchaser's acceptance for payment of such Shares, the Purchaser must be able to exercise full voting, consent and other rights with respect to such

Shares (and any and all Distributions), including voting at any meeting of Hawk's stockholders or executing a written consent concerning any matter.

The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, sell, assign and transfer the Shares tendered hereby (and any and all Distributions) and that, when the same are accepted for payment by the Purchaser, the Purchaser will acquire good, marketable and unencumbered title to such Shares (and any and all Distributions), free and clear of all liens, restrictions, charges and encumbrances and the same will not be subject to any adverse claims.

In addition, the undersigned shall remit and transfer promptly to the Depositary for the account of the Purchaser all Distributions in respect of the Shares tendered hereby, accompanied by appropriate documentation of transfer, and, pending such remittance and transfer or appropriate assurance thereof, the Purchaser shall be entitled to all rights and privileges as owner of each such Distribution and may withhold the entire purchase price of the Shares tendered hereby or deduct from such purchase price the amount or value of such Distribution as determined by the Purchaser in its sole discretion.

All authority herein conferred or agreed to be conferred shall survive the death or incapacity of the undersigned, and any obligation of the undersigned hereunder shall be binding upon the heirs, executors, administrators, personal representatives, trustees in bankruptcy, successors and assigns of the undersigned. Except as stated in the Offer to Purchase, this tender is irrevocable.

The undersigned understands that the Purchaser's acceptance for payment of Shares tendered pursuant to the Offer will constitute a binding agreement between the undersigned and the Purchaser upon the terms and subject to the conditions of the Offer (and if the Offer is extended or amended, the terms of or the conditions to any such extension or amendment).

Guarantee of Signature(s)
(If required; see Instructions 1 and 5)
(For use by Eligible Institutions only. Place medallion guarantee in space below)

1. Guarantee of Signatures. No signature guarantee is required on this Letter of Transmittal (a) if this Letter of Transmittal is signed by the registered holder(s) (which term, for purposes of this Instruction, includes any participant in DTC's system whose name appears on a security position listing as the owner of the Shares) of Shares tendered herewith, unless such holder has completed either the box entitled "Special Payment Instructions" or the box entitled "Special Delivery Instructions" on this Letter of Transmittal or (b) if such Shares are tendered for the account of a financial institution (including most commercial banks, savings and loan associations and brokerage houses) that is a member in good standing in the Security Transfer Agents Medallion Program or any other "eligible guarantor institution," as such term is defined in Rule 17Ad-15 under the Exchange Act (each, an "Eligible Institution"). In all other cases, all signatures on this Letter of Transmittal must be guaranteed by an Eligible Institution. See Instruction 5.

2. Requirements of Tender. In order for a stockholder to validly tender Shares pursuant to the Offer, this Letter of Transmittal (or a manually signed facsimile thereof), properly completed and duly executed, together with any required signature guarantees (or, in the case of a book-entry transfer, an Agent's Message in lieu of the Letter of Transmittal) and any other documents required by this Letter of Transmittal must be received by the Depositary at one of the addresses on the cover page of this Letter of Transmittal and either (A) the Share Certificates evidencing tendered Shares must be received by the Depositary at such address or (B) such Shares must be tendered pursuant to the procedure for book-entry transfer described in Section 3 of the Offer to Purchase and confirmation of a book-entry transfer of such Shares (a "Book-Entry Confirmation") must be received by the Depositary, in each case prior to the Expiration Time (as defined in Section 1 of the Offer to Purchase).

Stockholders whose Share Certificates are not immediately available, who cannot deliver their Share Certificates and all other required documents to the Depositary at or prior to the Expiration Time or who cannot complete the procedure for delivery by book-entry transfer at or prior to the Expiration Time may tender their Shares pursuant to the guaranteed delivery procedure described under Section 3—"Procedures for Accepting the Offer and Tendering Shares" in the Offer to Purchase. Pursuant to such procedure: (i) such tender must be made by or through an Eligible Institution; (ii) a properly completed and duly executed Notice of Guaranteed Delivery, substantially in the form made available by the Purchaser, must be received by the Depositary at one of the addresses on the cover page of this Letter of Transmittal at or prior to the Expiration Time; and (iii) the Share Certificates representing all physically delivered Shares in proper form for transfer by delivery, or Book-Entry Confirmation of all Shares delivered by book-entry transfer, in each case together with a Letter of Transmittal (or a manually signed facsimile thereof), properly completed and duly executed, with any required signature guarantees (or, in the case of a book-entry transfer, an Agent's Message), and any other documents required by this Letter of Transmittal, must be received by the Depositary at such address within three NYSE Amex trading days after the date of execution of such Notice of Guaranteed Delivery, all as described under Section 3—"Procedures for Accepting the Offer and Tendering Shares" in the Offer to Purchase.

The term "Agent's Message" means a message, transmitted by DTC to and received by the Depositary and forming a part of a Book-Entry Confirmation, that states that DTC has received an express acknowledgment from the participant in DTC tendering the Shares that are the subject of such Book-Entry Confirmation, that such participant has received and agrees to be bound by the terms of the Letter of Transmittal and that the Purchaser may enforce such agreement against such participant.

The method of delivery of Shares, the Letter of Transmittal and all other required documents, including delivery through DTC, is at the option and risk of the tendering stockholder, and the delivery of all such documents will be deemed made only when actually received by the Depositary

(including, in the case of a book-entry transfer, receipt of a Book-Entry Confirmation). If delivery is by mail, registered mail with return receipt requested, properly insured, is recommended. In all cases, sufficient time should be allowed to ensure timely delivery.

The Purchaser will not accept any alternative, conditional or contingent tenders, and no fractional Shares will be purchased. By executing this Letter of Transmittal (or facsimile thereof), the tendering stockholder waives any right to receive any notice of the acceptance for payment of the Shares.

3. Inadequate Space. If the space provided herein is inadequate, the Share Certificate numbers and/or the number of Shares should be listed on a separate schedule attached hereto.

4. Partial Tenders. If fewer than all the Shares represented by any Share Certificate delivered to the Depositary are to be tendered, fill in the number of Shares which are to be tendered in the box entitled "Total Number of Shares Tendered." In such case, a new certificate for the remainder of the Shares represented by the old certificate will be sent to the person(s) signing this Letter of Transmittal, unless otherwise provided in the appropriate box on this Letter of Transmittal, as promptly as practicable following the expiration or termination of the Offer. All Shares represented by certificates delivered to the Depositary will be deemed to have been tendered unless otherwise indicated.

(a) Exact Signatures. If this Letter of Transmittal is signed by the registered holder(s) of the Shares tendered hereby, the signature(s) must correspond with the name(s) as written on the face of the Share Certificates without alteration, enlargement or any change whatsoever.

(b) Joint Holders. If any of the Shares tendered hereby are held of record by two or more persons, all such persons must sign this Letter of Transmittal.

(c) Different Names on Certificates. If any of the Shares tendered hereby are registered in different names on different certificates, it will be necessary to complete, sign and submit as many separate Letters of Transmittal as there are different registrations of certificates.

(d) Endorsements. If this Letter of Transmittal is signed by the registered holder(s) of the Shares tendered hereby, no endorsements of certificates or separate stock powers are required unless payment of the purchase price is to be made, or Shares not tendered or not purchased are to be returned, in the name of any person other than the registered holder(s). Signatures on any such certificates or stock powers must be guaranteed by an Eligible Institution.

(e) Stock Powers. If this Letter of Transmittal is signed by a person other than the registered holder(s) of the Shares tendered hereby, certificates must be endorsed or accompanied by appropriate stock powers, in either case, signed exactly as the name(s) of the registered holder(s) appear(s) on the certificates for such Shares. Signature(s) on any such certificates or stock powers must be guaranteed by an Eligible Institution. See Instruction 1.

(f) Evidence of Fiduciary or Representative Capacity. If this Letter of Transmittal or any certificate or stock power is signed by a trustee, executor, administrator, guardian, attorney-in-fact, officer of a corporation or other person acting in a fiduciary or representative capacity, such person should so indicate when signing, and proper evidence satisfactory to the Depositary of the authority of such person so to act must be submitted.

6. Stock Transfer Taxes. Except as otherwise provided in this Instruction 6, the Purchaser or any successor entity thereto will pay all stock transfer taxes with respect to the transfer and sale of any Shares to it or its order pursuant to the Offer. If, however, payment of the purchase price is to be made to, or if Share Certificate(s) for Shares not tendered or not accepted for payment are to be registered in the name of, any person(s) other than the registered holder(s), or if tendered Share Certificate(s) are registered in the name of any person(s) other than the person(s) signing this Letter of Transmittal, the amount of any stock transfer taxes (whether imposed on the registered holder(s) or

such other person(s)) payable on account of the transfer to such other person(s) will be deducted from the purchase price of such Shares purchased unless evidence satisfactory to the Purchaser of the payment of such taxes, or exemption therefrom, is submitted.

Except as provided in this Instruction 6, it will not be necessary for transfer tax stamps to be affixed to the Share Certificate(s) evidencing the Shares tendered hereby.

7. Special Payment and Delivery Instructions. If a check is to be issued in the name of, and, if appropriate, Share Certificates for Shares not tendered or not accepted for payment are to be issued or returned to, any person(s) other than the signer of this Letter of Transmittal or if a check and, if appropriate, such Share Certificates are to be returned to any person(s) other than the person(s) signing this Letter of Transmittal or to an address other than that shown in this Letter of Transmittal, the appropriate boxes on this Letter of Transmittal must be completed.

8. Substitute Form W-9. To avoid backup withholding, a tendering stockholder is required to provide the Depositary with a correct Taxpayer Identification Number ("TIN") on Substitute Form W-9, which is provided under "Important Tax Information" below, and to certify, under penalties of perjury, that such number is correct and that such stockholder is not subject to backup withholding of federal income tax, and that such stockholder is a U.S. person (as defined for U.S. federal income tax purposes). If a tendering stockholder has been notified by the Internal Revenue Service ("IRS") that such stockholder is subject to backup withholding, such stockholder must cross out item (2) of the Certification box of the Substitute Form W-9, unless such stockholder has since been notified by the IRS that such stockholder is no longer subject to backup withholding. Failure to provide the information on the Substitute Form W-9 may subject the tendering stockholder to federal income tax withholding on the payment of the purchase price of all Shares purchased from such stockholder. If the tendering stockholder has not been issued a TIN and has applied for one or intends to apply for one in the near future, such stockholder should check the box in Part 3 of the Substitute Form W-9, and sign and date the Substitute Form W-9. If the box in Part 3 is checked and the Depositary is not provided with a TIN by the time of payment, the Depositary will withhold a portion of all payments of the purchase price to such stockholder until a TIN is provided to the Depositary.

Certain stockholders (including, among others, all corporations and certain foreign individuals and entities) may not be subject to backup withholding. Foreign stockholders should submit an appropriate and properly completed IRS Form W-8, a copy of which may be obtained from the Depositary, in order to avoid backup withholding. Such stockholders should consult a tax advisor to determine which Form W-8 is appropriate. See the enclosed "Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9" for more instructions.

9. Irregularities. All questions as to the validity, form, eligibility (including time of receipt) and acceptance for payment of any tender of Shares, shall be interpreted by the Purchaser, in the Purchaser's sole discretion, subject to the right of any party to seek judicial review in accordance with applicable law. No such determination shall be deemed to be final and binding on the parties unless such determination has been finally determined by a court of competent jurisdiction, with respect to which all appeals have been taken or waived. The Purchaser reserves the absolute right to reject any and all tenders determined by the Purchaser not to be in proper form or the acceptance for payment of which may, in the Purchaser's opinion, be unlawful. The Purchaser also reserves the absolute right to waive any defect or irregularity in the tender of any Shares of any particular stockholder, whether or not similar defects or irregularities are waived in the case of other stockholders. No tender of Shares will be deemed to have been validly made until all defects and irregularities have been cured or waived to our satisfaction. None of the Purchaser, Parent, the Depositary, the Information Agent, the Dealer Manager or any other person will be under any duty to give notification of any defects or irregularities in tenders or incur any liability for failure to give any such notification. The Purchaser will interpret, in the Purchaser's sole discretion, the terms and conditions of the Offer (including the Letter of Transmittal and the instructions thereto), subject to the right of any party to seek judicial review in

accordance with applicable law. No such determination shall be deemed to be final and binding on the parties unless such determination has been finally determined by a court of competent jurisdiction, with respect to which all appeals have been taken or waived.

10. Requests for Additional Copies. Questions and requests for assistance or additional copies of the Offer to Purchase, this Letter of Transmittal and the Notice of Guaranteed Delivery should be directed to the Information Agent at its telephone numbers and address set forth below.

11. Lost, Destroyed or Stolen Certificates. If any certificate representing Shares has been lost, destroyed or stolen, the stockholder should promptly notify Computershare Investor Services, LLC as Transfer Agent at (800) 622-6757. The stockholder will then be instructed as to the steps that must be taken in order to replace the certificate(s). This Letter of Transmittal and related documents cannot be processed until the procedures for replacing lost or destroyed certificates have been followed.

IMPORTANT: THIS LETTER OF TRANSMITTAL (OR FACSIMILE THEREOF), TOGETHER WITH ANY REQUIRED SIGNATURE GUARANTEES, OR, IN THE CASE OF A BOOK-ENTRY TRANSFER, AN AGENT'S MESSAGE, AND ANY OTHER REQUIRED DOCUMENTS, MUST BE RECEIVED BY THE DEPOSITARY AT OR PRIOR TO THE EXPIRATION TIME, AND EITHER CERTIFICATES FOR TENDERED SHARES MUST BE RECEIVED BY THE DEPOSITARY OR SHARES MUST BE DELIVERED PURSUANT TO THE PROCEDURES FOR BOOK-ENTRY TRANSFER, IN EACH CASE AT OR PRIOR TO THE EXPIRATION TIME, OR THE TENDERING STOCKHOLDER MUST COMPLY WITH THE PROCEDURES FOR GUARANTEED DELIVERY.

Under federal income tax law, a stockholder who is a U.S. person (as defined for U.S. federal income tax purposes) surrendering Shares must, unless an exemption applies, provide the Depositary (as payer) with the stockholder's correct TIN on IRS Form W-9 or on the Substitute Form W-9 included in this Letter of Transmittal. If the stockholder is an individual, the stockholder's TIN is such stockholder's Social Security number. If the correct TIN is not provided, the stockholder may be subject to a $50 penalty imposed by the IRS and payments of cash to the stockholder (or other payee) pursuant to the Offer may be subject to backup withholding of a portion of all payments of the purchase price.

Certain stockholders (including, among others, corporations and certain foreign individuals and entities) may not be subject to backup withholding and reporting requirements. In order for an exempt foreign stockholder to avoid backup withholding, such person should complete, sign and submit an appropriate Form W-8 signed under penalties of perjury, attesting to his or her exempt status. A Form W-8 can be obtained from the Depositary. Such stockholders should consult a tax advisor to determine which Form W-8 is appropriate. Exempt stockholders, other than foreign stockholders, should furnish their TIN, check the box in Part 4 of the Substitute Form W-9 and sign, date and return the Substitute Form W-9 to the Depositary in order to avoid erroneous backup withholding. See the enclosed "Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9" for additional instructions.

If backup withholding applies, the Depositary is required to withhold and pay over to the IRS a portion of any payment made to a stockholder. Backup withholding is not an additional tax. Rather, the federal income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If backup withholding results in an overpayment of taxes, a refund may be obtained from the IRS.

To prevent backup withholding on payments that are made to a stockholder with respect to Shares purchased pursuant to the Offer, the stockholder is required to notify the Depositary of the stockholder's correct TIN by completing the Substitute Form W-9 included in this Letter of Transmittal certifying (1) that the TIN provided on the Substitute Form W-9 is correct (or that such stockholder is awaiting a TIN), (2) that the stockholder is not subject to backup withholding because (i) the stockholder is exempt from backup withholding, (ii) the stockholder has not been notified by the IRS that the stockholder is subject to backup withholding as a result of a failure to report all interest and dividends or (iii) the IRS has notified the stockholder that the stockholder is no longer subject to backup withholding and (3) the stockholder is a U.S. person (as defined for U.S. federal income tax purposes).

The tendering stockholder is required to give the Depositary the TIN, generally the Social Security number or Employer Identification Number, of the record holder of the Shares tendered hereby. If the Shares are in more than one name or are not in the name of the actual owner, consult the enclosed "Guidelines for Certification of Taxpayer Identification Number on Substitute W-9" for additional guidance on which number to report. If the tendering stockholder has not been issued a TIN and has applied for a number or intends to apply for a number in the near future, such stockholder should check the box in Part 3 of the Substitute Form W-9, sign and date the Substitute Form W-9 and sign and date the Certificate of Awaiting Taxpayer Identification Number, which appears in a separate box below the Substitute Form W-9. If the box in Part 3 of the Substitute Form W-9 is checked and the Depositary is not provided with a TIN by the time of payment, the Depositary will withhold a portion of all payments of the purchase price until a TIN is provided to the Depositary. If the Depositary is

provided with an incorrect TIN in connection with such payments, the stockholder may be subject to a $50.00 penalty imposed by the IRS.

Please consult your accountant or tax advisor for further guidance regarding the completion of IRS Form W-9 or IRS Form W-8 to claim exemption from backup withholding, or contact the Depositary.

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

(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) 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.

(3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION—Falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.
