Thank you, Jack. And today I'll cover the financial results for the first quarter, as we set our outlook for the second quarter and full year 2019. Total revenue for the first quarter was $48.5 million, representing growth of 53%. Recurring revenues from subscription and support grew 62% year-over-year to $45 million. Professional services revenue was $2.9 million for the quarter at 26% year-over-year increase. And perpetual license revenue was $0.7 million for the first quarter or a decrease of 60% year-over-year. Moving down to P&L to gross margins. Overall gross margin was 70% during the first quarter, and our product gross margins remain strong at 71%, or 76% when adding back depreciation of equipment, amortization of acquired intangible assets, which we refer to as cash gross margins. Our professional services gross margins were 47%, now that we have the newer acquisitions in model, and our target is 40% margins, so we're actually over our target for professional services margins here in Q1. Turning to our operating expenses. Research and development expense, net of refundable Canadian tax credits was $6.3 million for the first quarter, representing 13% of total revenue. Sales and marketing expense was $7 million, representing 14% of total revenue for the first quarter. General and administrative expense was $10 million in the first quarter, representing 21% of total revenue. However, excluding noncash stock compensation expense, G&A expense was $6 million or 12% of total revenue. Acquisition-related expenses were $7.7 million in the first quarter, resulting from our recent significant international expansion activity. I'll note here that we closed the PostUp acquisition in April, as Jack mentioned. So we will have some new acquisition-related expenses starting in Q2 for PostUp in addition to the transformation expenses related to Rant & Rave and Adestra acquired in Q4. Acquisition related expenses, as you know, taper off to $0 during the 4 quarters following an acquisition unless or until we have additional acquisition activity. Operating loss was $2.6 million in the first quarter compared to a loss of $0.5 million for the same period in 2018. GAAP net loss was $7.8 million or a loss of $0.38 per share compared to GAAP net loss of $3.2 million or a loss of $0.16 per share in the first quarter of 2018. Non-GAAP net income was $11.1 million or $0.53 per share in the first quarter of 2019 compared to non-GAAP net income of $7.7 million or $0.37 per share in the first quarter of 2018. Our first quarter 2019 adjusted EBITDA was $17.8 million or 37% of total revenue, up 65% compared to $10.8 million or 34% of total revenue for the same period last year. Now onto our balance sheet and statement of cash flows. We ended the first quarter with $14 million in cash. Cash flows provided by operating activities were $4.9 million for Q1. And of course, it would have been much higher without the acquisition-related expenses paid in the period. Furthermore, Upland is cash efficient when looking at income taxes and capital expenditures. Cash taxes in Q1 '19 were $0.8 million compared to cash taxes of $1 million in Q1 of 2018. Upland currently has approximately $135 million of usable tax NOLs, which is comprised of $115 million of U.S. federal tax NOLs and $20 million of U.K. tax NOLs. We expect to continue to pay around $4 million per year in cash taxes, mostly in the form of Canada revenue agency income taxes, Ireland income taxes and some U.S. state income taxes. We currently have approximately $321 million of gross debt outstanding, making net debt of approximately $307 million. We now have approximately $75 million of available capacity on our existing credit facility including the uncommitted accordion, so we have dry powder for the next acquisition. For the quarter ending June 30, 2019, Upland expects reported total revenue to be between $49.9 million and $51.9 million, including subscription and support revenue between $46.7 million and $48.3 million for growth in recurring revenue of 43% at the midpoint over the quarter ended June 30, 2018. Second quarter 2019 adjusted EBITDA is expected to be between $17.7 million and $18.7 million for an adjusted EBITDA margin of roughly 36% at the midpoint, representing growth of 45% at the midpoint over the quarter ended June 30, 2018. For the full year, ending December 31, 2019, Upland expects reported total revenue to be between $202.4 million and $206.4 million, including subscription and support revenue between $189.2 million and $192.4 million for growth in recurring revenue of 40% at the midpoint over the year ended December 31, 2018. Full year 2019 adjusted EBITDA is expected to be between $73.7 million and $76.1 million for an adjusted EBITDA margin of 37% at the midpoint, representing growth of 41% at the midpoint over the year ended December 31, 2018. And with that, I'll turn the call over to Tim Mattox, our President and COO.
