The foregoing indemnity agreement is in addition to any liability which the Company may otherwise have to the Underwriter (or any such affiliate thereof), director, officer, employee or controlling person of the Underwriter.

(b) Each Selling Stockholder, severally and not jointly, shall indemnify and hold harmless the Company, the Underwriter and any affiliate thereof that assists the Underwriter in the distribution of the Shares in the Offering, and each of their respective directors, officers and employees, and each person, if any, who controls the Company or the Underwriter (or any such affiliate thereof) within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Stock), to which the Company, the Underwriter, or any such director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in (A) any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto (in the case of any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus, in light of the circumstances under which such statements were made) or (B) in any Permitted Issuer Information, any Marketing Materials or any “free writing prospectus” (as defined

The liability of the Selling Stockholder under the indemnity agreement contained in this paragraph shall be limited to an amount equal to the total gross proceeds from the offering of the shares of the Stock purchased under the Agreement received by the Selling Stockholder, as set forth in the table on the cover page of the Prospectus. The foregoing indemnity agreement is in addition to any liability that the Selling Stockholders may otherwise have to the Company, the Underwriter (or any affiliate thereof), director, officer, employee or controlling persons.

(c) The Underwriter shall indemnify and hold harmless the Company, each Selling Stockholder, their respective directors (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company), officers and employees, and each person, if any, who controls the Company or such Selling Stockholder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company, such Selling Stockholder or any such director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Marketing Materials or Blue Sky Application, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Marketing Materials or

Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning the Underwriter furnished to the Company by or on behalf of the Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 10(f). The foregoing indemnity agreement is in addition to any liability that the Underwriter may otherwise have to the Company, such Selling Stockholder or any such director, officer, employee or controlling person.

(d) Promptly after receipt by an indemnified party under this Section 10 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 10, notify the indemnifying party in writing of the claim or the commencement of that action; provided, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 10 except to the extent it has been materially prejudiced (through the forfeiture of substantive rights and defenses) by such failure and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 10. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 10 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, that the indemnified party shall have the right to employ counsel to represent jointly the indemnified party and those other indemnified parties and their respective directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought under this Section 10 if (i) the indemnified party and the indemnifying party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party and its directors, officers, employees and controlling persons shall have reasonably concluded that there may be legal defenses available to them that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties or their respective directors, officers, employees or controlling persons, on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would present such counsel with an actual or potential conflict of interest and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party. No indemnifying party shall (x) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or

contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include a statement as to, or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party, or (y) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 10(a) or (b) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the date of such settlement.

(e) If the indemnification provided for in this Section 10 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 10(a), 10(b), or 10(c) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company and the Selling Stockholders, on the one hand, and the Underwriter, on the other, from the offering of the Stock, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Selling Stockholders, on the one hand, and the Underwriter, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholders, on the one hand, and the Underwriter, on the other hand, in connection with the offering of Stock shall be deemed to be in the same respective proportion as the total net proceeds from the offering of the Stock purchased under this Agreement (before deducting expenses) received by the Company and the Selling Stockholders, on the one hand, and the total underwriting discounts and commissions received by the Underwriter with respect to the shares of the Stock purchased under this Agreement, in each case as set forth in the table on the cover page of the Prospectus, on the other hand. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company, the Selling Stockholders or the Underwriter, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Selling Stockholders

and the Underwriter agree that it would not be just and equitable if contributions pursuant to this Section 10(e) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 10(e) shall be deemed to include, for purposes of this Section 10(e), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 10(e), in no event shall the Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by the Underwriter with respect to the offering of the Stock exceeds the amount of any damages that the 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.

Ladies and Gentlemen:

The undersigned understands that you (the “Underwriter”), propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) providing for the purchase by the Underwriter of shares (the “Shares”) of common stock, par value $0.01 per share (the “Common Stock”) of Paycom Software, Inc., a Delaware corporation (the “Company”) and that the Underwriter proposes to reoffer the Shares to the public pursuant to a Registration Statement on Form S-3 filed with the Securities and Exchange Commission on May 14, 2015 (the “Offering”).

In consideration of the execution of the Underwriting Agreement by the Underwriter, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, without the prior written consent of the Underwriter, the undersigned will not, directly or indirectly, (1) offer for sale, sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any shares of Common Stock (including, without limitation, shares of Common Stock that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and shares of Common Stock that may be issued upon exercise of any options or warrants) or securities convertible into

or exercisable or exchangeable for, or that represent the right to receive shares of, Common Stock, other than any Shares that may be sold in the Offering, (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of shares of Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise, (3) cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any shares of Common Stock or securities convertible into or exercisable or exchangeable for Common Stock or any other securities of the Company, or (4) publicly disclose the intention to do any of the foregoing, each for a period commencing on the date hereof and ending on the 45^th day after the date of the final prospectus supplement relating to the Offering (such 45-day period, the “Lock-Up Period”).

The foregoing paragraph shall not apply to (a) transactions relating to shares of Common Stock or other securities acquired in the open market after the completion of the Offering; provided, that such transaction shall not require a filing under Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the undersigned shall agree to not voluntarily make any filing or public announcement of any such sale, pledge, transfer or other disposition prior to the expiration of the Lock-Up Period; (b) bona fide gifts, sales, transfers or other dispositions of shares of any class of the Company’s capital stock, including by will or intestacy, in each case that are made exclusively between and among the undersigned and members of the undersigned’s family, a trust established for the benefit of the undersigned’s family, affiliates of the undersigned, including its partners (if a partnership), members (if a limited liability company) or stockholders (if a corporation), or another corporation, partnership, investment fund or other business entity that is controlled or managed by an affiliate of the undersigned; provided, that it shall be a condition to any transfer pursuant to this clause (b) that (i) the transferee/donee agrees to be bound by the terms of this Lock-Up Agreement (including, without limitation, the restrictions set forth in the preceding paragraph) to the same extent as if the transferee/donee were a party hereto, (ii) each party (donor, donee, transferor or transferee) shall not be required by law (including without limitation the disclosure requirements of the Securities Act of 1933, as amended (the “Securities Act”), and the Exchange Act to make, and shall agree to not voluntarily make, any filing or public announcement of the transfer or disposition prior to the expiration of the Lock-Up Period referred to above; provided, that the foregoing restriction in clause (b)(ii) shall not be deemed to apply to any distributions of shares of Common Stock made by Welsh, Carson, Xxxxxxxx & Xxxxx, X.X. or an affiliate thereof to its limited partners to the extent that any such filing or public announcement indicate that such transfer is not a sale, and (iii) the undersigned notifies the Underwriter at least two business days prior to the proposed gift, sale, transfer or disposition; (c) the exercise of warrants or stock options granted pursuant to the Company’s stock option/incentive plans or the conversion of securities convertible into, or exchangeable or exercisable for, Common Stock, otherwise outstanding on the date hereof; provided, that the restrictions contained in this Lock-Up Agreement shall apply to shares of Common Stock issued upon such exercise or conversion; (d) the transfer of Common Stock to the Company in a

transaction exempt from Section 16(b) of the Exchange Act, solely in connection with the payment of taxes due in connection with any exercise of securities convertible into Common Stock or any vesting of Common Stock; provided, that no such transfer of the undersigned’s shares of Common Stock to the Company pursuant to the exercise of such right shall require a filing under Section 16 of the Exchange Act with respect to any of the undersigned’s shares of Common Stock during the Lock-Up Period; (e) the establishment or modification of any contract, instruction or plan that satisfies all of the requirements of Rule 10b5-1 (a “Rule 10b5-1 Plan”) under the Exchange Act; provided, that no sales of Common Stock or securities convertible into, or exchangeable or exercisable for, Common Stock, shall be made pursuant to a Rule 10b5-1 Plan prior to the expiration of the Lock-Up Period; provided further, that neither the undersigned nor the Company is required to report the establishment of such Rule 10b5-1 Plan in any public report or filing with the Commission under the Exchange Act during the lock-up period and does not otherwise voluntarily effect any such public filing or report regarding such Rule 10b5-1 Plan; (f) any demands or requests for, exercises of any right with respect to, or taking of any action in preparation of, the registration by the Company under the Securities Act of the undersigned’s shares of Common Stock; provided, that no transfer of the undersigned’s shares of Common Stock registered pursuant to the exercise of any such right and no registration statement shall be filed under the Securities Act with respect to any of the undersigned’s shares of Common Stock during the Lock-Up Period; (g) the transfer of shares of Common Stock by operation of law, such as pursuant to a qualified domestic order or in connection with a divorce settlement; provided, that each such transferee executes an agreement stating that the transferee is receiving and holding such Shares subject to the restrictions contained in this Lock-Up Agreement; and (h) the transfer of Common Stock to the Company or its subsidiaries from an executive officer of the Company upon such executive officer’s death, disability or termination of employment. Furthermore, the restrictions contained herein shall not apply to any transfers, sales, tenders or other dispositions of any of the undersigned’s Shares pursuant to a tender offer made to all holders of the Company’s securities for securities of the Company that would, if consummated, result in not less than a majority of the outstanding voting securities of the Company being disposed in such transaction or pursuant to any other transaction, including, without limitation, a merger, consolidation or other business combination, resulting in not less than a majority of the outstanding voting securities of the Company being disposed in such transaction (including, without limitation, entering into any lock-up, voting or similar agreement pursuant to which the undersigned may agree to transfer, sell, tender or otherwise dispose of any of the undersigned’s Shares in connection with any such transaction or to vote any of the undersigned’s Shares in favor of any such transaction); provided that, if such tender offer or other transaction is not completed, any of the undersigned’s Shares subject to this Lock-Up Agreement shall remain subject to the restrictions contained in this Lock-Up Agreement.

In furtherance of the foregoing, the Company and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Agreement.

The undersigned understands that the Company and the Underwriter will proceed with the Offering in reliance on this Lock-Up Agreement.

Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to the Underwriting Agreement, the terms of which are subject to negotiation between the Company, the Selling Stockholders named therein and the Underwriter.

This Lock-Up Agreement shall automatically terminate, and the undersigned will, in each case, be released from its obligations under this Lock-Up Agreement upon the earliest to occur, if any, of (1) written notice from the Company on the one hand, or the Underwriter, on the other hand, notifying the other in writing that it does not intend to proceed with the Offering prior to the execution of the Underwriting Agreement; (2) the termination of the Underwriting Agreement (other than the provisions thereof which survive termination) before the payment for and delivery of any Shares to the Underwriter; or (3) October 1, 2015, in the event that the Underwriting Agreement has not been executed by such date. This agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

[Signature page follows]

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.
